Rename debug_print_query to log_statement and rename show_query_stats to
show_statement_stats.

pointed out by Barry Lind: UPDATE bigintcol = 10000000000 fails because
the constant is initially taken as float8. We really need a better way,
but it's not gonna happen for 7.3.
Also, remove int4reltime() function, which is redundant with the
existing binary-compatibility coercion path from int4 to reltime,
and probably has been unreachable code for a long while.

type for runtime constraint checks, instead of misusing the parse-time
Constraint node for the purpose. Fix some damage introduced into type
coercion logic; in particular ensure that a coerced expression tree will
read out the correct result type when inspected (patch had broken some
RelabelType cases). Enforce domain NOT NULL constraints against columns
that are omitted from an INSERT.

available (else there's no way to interpret the list links). Change
pg_locks view to show transaction ID locks separately from ordinary
relation locks. Avoid showing N duplicate rows when the same lock is
held multiple times (seems unlikely that users care about exact hold
count). Improve documentation.

functions, per suggestion from John Gray and Joe Conway. Also, fix
plpgsql RETURN NEXT to verify that returned values match the expected
tupdesc.

to false provides more SQL-spec-compliant behavior than we had before.
I am not sure that setting it false is actually a good idea yet; there
is a lot of client-side code that will probably be broken by turning
autocommit off. But it's a start.
Loosely based on a patch by David Van Wie.

column additions, deletions, and renames that would let a child table
get out of sync with its parent. Patch by Alvaro Herrera, with some

I've attached a patch which should fix these problems.

connections by the superuser only.
This patch replaces the last patch I sent a couple of days ago.
It closes a connection that has not been authorised by a superuser if it would
leave less than the GUC variable ReservedBackends
(superuser_reserved_connections in postgres.conf) backend process slots free
in the SISeg. This differs to the first patch which only reserved the last
ReservedBackends slots in the procState array. This has made the free slot
test more expensive due to the use of a lock.
After thinking about a comment on the first patch I've also made it a fatal
error if the number of reserved slots is not less than the maximum number of
connections.

to the table function, thus preventing memory leakage accumulation across
calls. This means that SRFs need to be careful to distinguish permanent
and local storage; adjust code and documentation accordingly. Patch by
Joe Conway, very minor tweaks by Tom Lane.

when it finds an existing relation with the same name as the
to-be-created index.
Old error message:
nconway=# create table foo (a int);
CREATE TABLE
nconway=# create index foo on foo (a);
ERROR: index named "foo" already exists
I replaced 'index' with 'relation' in the error message.

should be pretty safe in practice, but it's probably better to be safe
than sorry.
I was actually looking for cases where NAMEDATALEN is assumed to be
32, but only found one. That's fixed too, as well as a few bits of
code cleanup.

CVS HEAD):
Amended "strings" regression test. TOAST tests now insert two values
with storage set to "external", to exercise properly the TOAST slice
routines which fetch only a subset of the chunks.
Changed now-misleading comment on AlterTableCreateToastTable in
tablecmds.c, because both columns of the index on a toast table are now
used.

copying into a fixed-size buffer (in this case, a buffer of
NAMEDATALEN bytes). AFAICT nothing to worry about here, but worth
fixing anyway...

bit on the indexes.
I also attach clusterdb and clusterdb.sgml; both of them are blatant
rips of vacuumdb and vacuumdb.sgml, but get the job done. Please review
them, as I'm probably making a lot of mistakes with SGML and I can't
compile it here.
vacuumdb itself is not very comfortable to use when the databases have
passwords, because it has to connect once for each table (I can probably
make it connect only once for each database; should I?). Because of
this I added a mention of PGPASSWORDFILE in the documentation, but I
don't know if that is the correct place for that.
