The term "super-exclusive lock" is an acceptable synonym of "cleanup
lock". Even still, switching from one term to the other in the same
file is confusing. Standardize on "cleanup lock" within vacuumlazy.c.
Per a complaint from Andres Freund.

Update vacuumlazy.c file header comments (as well as comments above the
lazy_scan_heap function) that were largely written before the
introduction of the HOT optimization, when lazy_scan_heap did far less,
and didn't actually prune during its initial heap pass.
Since lazy_scan_heap now outsources far more work to lower level
functions, it makes sense to introduce the function by talking about the
high level invariant that dictates the order in which each phase takes
place. Also deemphasize the case where we run out of memory for TIDs,
since delaying that discussion makes it easier to talk about issues of
central importance.
Finally, remove discussion of parallel VACUUM from header comments.
These don't add much, and are in the wrong place.

Commit 2fd8685e7f simplified the checking of modified attributes that
takes place within heap_update(). This included a micro-optimization
affecting pages marked PD_PAGE_FULL: don't even try to use HOT to save a
few cycles on determining HOT safety. The assumption was that it won't
work out this time around, since it can't have worked out last time
around.
Remove the micro-optimization. It could only ever save cycles that are
consumed by the vast majority of heap_update() calls, which hardly seems
worth the added complexity. It also seems quite possible that there are
workloads that will do worse over time by repeated application of the
micro-optimization, despite saving some cycles on average, in the short
term.

In commit ff9f111bce24 I mixed up inconsistent definitions of the LSN of
the first record in a page, when the previous record ends exactly at the
page boundary. The correct LSN is adjusted to skip the WAL page header;
I failed to use that when setting XLogReaderState->overwrittenRecPtr,
so at WAL replay time VerifyOverwriteContrecord would refuse to let
replay continue past that record.

Replica identities that depend directly on an index rely on a set of
properties, one of them being that all the columns defined in this index
have to be marked as NOT NULL. There was a hole in the logic with ALTER
TABLE DROP NOT NULL, where it was possible to remove the NOT NULL
property of a column part of an index used as replica identity, so block
it to avoid problems with logical decoding down the road.
The same check was already done columns part of a primary key, so the
fix is straight-forward.

The emulation of fstat() in win32stat.c caused two issues with the
existing in-core callers, failing on EINVAL when using a stream as
argument:
- psql's \copy would crash when using a stream.
- pg_recvlogical would fail with -f -.
The tests in copyselect.sql from the main test suite covers the first
case, and there is a TAP test for the second case. However, in both
cases, as the standard streams are always redirected, automated tests
did not notice those issues, requiring a terminal on Windows to be
reproducible.
This issue has been introduced in bed9075, and the origin of the problem
is that GetFileInformationByHandle() does not work directly on streams,
so this commit adds an extra code path to emulate and return a set of
stats that match best with the reality. Note that redirected streams
rely on handles that can be queried with GetFileInformationByHandle(),
but we can rely on GetFinalPathNameByHandleA() to detect this case.

In most places, the variables necessarily store the same value as the
eponymous members of the XLogReaderState that we use during WAL
replay, because ReadRecord() assigns the values from the structure
members to the global variables just after XLogReadRecord() returns.
However, XLogBeginRead() adjusts the structure members but not the
global variables, so after XLogBeginRead() and before the completion
of XLogReadRecord() the values can differ. Otherwise, they must be
identical. According to my analysis, the only place where either
variable is referenced at a point where it might not have the same
value as the structure member is the refrence to EndRecPtr within
XLogPageRead.
Therefore, at every other place where we are using the global
variable, we can just switch to using the structure member instead,
and remove the global variable. However, we can, and in fact should,
do this in XLogPageRead() as well, because at that point in the code,
the global variable will actually store the start of the record we
want to read - either because it's where the last WAL record ended, or
because the read position has been changed using XLogBeginRead since
the last record was read. The structure member, on the other hand,
will already have been updated to point to the end of the record we
just read. Elsewhere, the latter is what we use as an argument to
emode_for_corrupt_record(), so we should do the same here.
This part of the patch is perhaps a bug fix, but I don't think it has
any important consequences, so no back-patch. The point here is just
to continue to whittle down the entirely excessive use of global
variables in xlog.c.

rescanLatestTimeLine() contains a guard against switching to
a timeline that forked off from the current one prior to the
current recovery point, but that guard does not work if the
timeline switch occurs before the first WAL recod (which must
be the checkpoint record) is read. Without this patch, an
improper timeline switch is therefore possible in such cases.
This happens because rescanLatestTimeLine() relies on the global
variable EndRecPtr to understand the current position of WAL
replay. However, EndRecPtr at this point in the code contains
the endpoint of the last-replayed record, not the startpoint or
endpoint of the record being replayed now. Thus, before any
records have been replayed, it's zero, which causes the sanity
check to always pass.
To fix, pass down the correct timeline explicitly. The
EndRecPtr value we want is the one from the xlogreader, which
will be the starting position of the record we're about to
try to read, rather than the global variable, which is the
ending position of the last record we successfully read.
They're usually the same, but not in the corner case described
here.
No back-patch, because in v14 and earlier branhes, we were using
the wrong TLI here as well as the wrong LSN. In master, that was
fixed by commit 4a92a1c3d1c361ffb031ed05bf65b801241d7cdd, but
that and it's prerequisite patches are too invasive to
back-patch for such a minor issue.

Memoize would always use the hash equality operator for the cache key
types to determine if the current set of parameters were the same as some
previously cached set. Certain types such as floating points where -0.0
and +0.0 differ in their binary representation but are classed as equal by
the hash equality operator may cause problems as unless the join uses the
same operator it's possible that whichever join operator is being used
would be able to distinguish the two values. In which case we may
accidentally return in the incorrect rows out of the cache.
To fix this here we add a binary mode to Memoize to allow it to the
current set of parameters to previously cached values by comparing
bit-by-bit rather than logically using the hash equality operator. This
binary mode is always used for LATERAL joins and it's used for normal
joins when any of the join operators are not hashable.

When a stored expression depends on a user-defined cast, the backend
records the dependency as being on the cast's implementation function
--- or indeed, if there's no cast function involved but just
RelabelType or CoerceViaIO, no dependency is recorded at all. This
is problematic for pg_dump, which is at risk of dumping things in the
wrong order leading to restore failures. Given the lack of previous
reports, the risk isn't that high, but it can be demonstrated if the
cast is used in some view whose rowtype is then used as an input or
result type for some other function. (That results in the view
getting hoisted into the functions portion of the dump, ahead of
the cast.)
A logically bulletproof fix for this would require including the
cast's OID in the parsed form of the expression, whence it could be
extracted by dependency.c, and then the stored dependency would force
pg_dump to do the right thing. Such a change would be fairly invasive,
and certainly not back-patchable. Moreover, since we'd prefer that
an expression using cast syntax be equal() to one doing the same
thing by explicit function call, the cast OID field would have to
have special ignored-by-comparisons semantics, making things messy.
So, let's instead fix this by a very simple hack in pg_dump: change
the object-type priority order so that casts are initially sorted
before functions, immediately after types. This fixes the problem
in a fairly direct way for casts that have no implementation function.
For those that do, the implementation function will be hoisted to just
before the cast by the dependency sorting step, so that we still have
a valid dump order. (I'm not sure that this provides a full guarantee
of no problems; but since it's been like this for many years without
any previous reports, this is probably enough to fix it in practice.)

Per buildfarm.

|
If a table contains a generated column that's preceded by a dropped
column, dumpTableData_insert failed to account for the dropped
column, and would emit DEFAULT placeholder(s) in the wrong column(s).
This resulted in failures at restore time. The default COPY code path
did not have this bug, likely explaining why it wasn't noticed sooner.
While we're fixing this, we can be a little smarter about the
situation: (1) avoid unnecessarily fetching the values of generated
columns, (2) omit generated columns from the output, too, if we're
using --column-inserts. While these modes aren't expected to be
as high-performance as the COPY path, we might as well be as
efficient as we can; it doesn't add much complexity.

Commit ac9099fc1 rearranged the logic in spgGetCache() that determines
the index's attType (nominal input data type) and leafType (actual
type stored in leaf index tuples). Turns out this broke things for
the case where (a) the actual input data type is different from the
nominal type, (b) the opclass's config function leaves leafType
defaulted, and (c) the opclass has no "compress" function. (b) caused
us to assign the actual input data type as leafType, and then since
that's not attType, we complained that a "compress" function is
required. For non-polymorphic opclasses, condition (a) arises in
binary-compatible cases, such as using SP-GiST text_ops for a varchar
column, or using any opclass on a domain over its nominal input type.
To fix, use attType for leafType when the index's declared column type
is different from but binary-compatible with attType. Do this only in
the defaulted-leafType case, to avoid overriding any explicit
selection made by the opclass.

We use "clang" to compile bitcode files for LLVM inlining. That might
be different from the build's main C compiler, so it needs its own set
of compiler flags. To simplify configure, we don't bother adding any
-W switches to that flag set; there's little need since the main build
will show us any warnings. However, if we don't want to see unwanted
warnings, we still have to add any -Wno-warning switches we'd normally
use with clang.
This escaped notice before commit 9ff47ea41, which tried to add
-Wno-compound-token-split-by-macro; buildfarm animals using mismatched
CC and CLANG still showed those warnings. I'm not sure why we never
saw any effects from the lack of -Wno-unused-command-line-argument
(maybe that's only activated by -Wall?). clang does not currently
support -Wno-format-truncation or -Wno-stringop-truncation, although
in the interests of future-proofing and consistency I included tests
for those.
Back-patch to v11 where we started building bitcode files.

Per buildfarm member prion, that runs the regression tests under a role
name that uses a hyphen. Issue introduced by 835bcba.

This commit adds to the main regression test suite a table with all
the in-core data types (some exceptions apply). This table is not
dropped, so as pg_upgrade would be able to check the binary
compatibility of the types tracked in the table. If a new type is added
in core, this part of the tests would need a refresh but the tests are
designed to fail if that were to happen.
As this is useful for upgrades and that these rely on the objects
created in the regression test suite of the old version upgraded from,
a backpatch down to 12 is done, which is the last point where a binary
incompatible change has been done (7c15cef). This will hopefully be
enough to find out if something gets broken during the development of a
new version of Postgres, so as it is possible to take actions in
pg_upgrade itself in this case (like 0ccfc28 for sql_identifier).
An area that is not covered yet is related to external modules, which
may create their own types. The testing infrastructure of pg_upgrade is
not integrated yet with the external modules stored in core
(src/test/modules/ or contrib/, all use the same database name for their
tests so there would be an overlap). This could be improved in the
future.

Up to now, you couldn't escape out of psql's \password command
by typing control-C (or other local spelling of SIGINT). This
is pretty user-unfriendly, so improve it. To do so, we have to
modify the functions provided by pg_get_line.c; but we don't
want to mess with psql's SIGINT handler setup, so provide an
API that lets that handler cause the cancel to occur.
This relies on the assumption that we won't do any major harm by
longjmp'ing out of fgets(). While that's obviously a little shaky,
we've long had the same assumption in the main input loop, and few
issues have been reported.
psql has some other simple_prompt() calls that could usefully
be improved the same way; for now, just deal with \password.
Nathan Bossart, minor tweaks by me
