Use safer allocation routines in more places of the tree

2026-08-17T07:15:45Z

This is part of a more global effort to modernize the code tree with safer allocation functions, which offer more protection in terms of: - stronger type safety guarantees - size overflow checks, particulary for arrays. This set of updates includes allocation changes based on palloc_object(), palloc_array() and repalloc_array(). This work is similar to 1b105f9472bd, expanding more the new APIs in the tree in an incremental fashion.

Add dshash_get_dsa_area(), able to retrieve the DSA area of a dshash table

2026-08-03T11:05:23Z

Code using GetNamedDSHash() to retrieve a dshash table may also want to limit its size, but there is actually no easy way to do so because the dsa_area of a hash table is hidden within dshash.c. This commit adds dshash_get_dsa_area() to close the gap, which returns the dsa_area for a given dshash_table. The DSA area retrieved can then be passed to dsa_set_size_limit(), to limit its size. This accessor routine also opens the door for allocating additional objects in the same DSA area as a hash table, which may be useful for some.

Fix for loop variables

2026-07-11T12:39:15Z

A number of for loops used loop variables that did not match the type of the end condition. This could lead to wraparound or signed/unsigned mismatches. Probably none of these are a problem in practice, but it's fragile code.

Pre-beta mechanical code beautification, step 1: run pgindent.

2026-05-13T14:34:17Z

Update typedefs.list from the buildfarm, and run pgindent. The changes from the new typedefs list are pretty minimal, since we'd been pretty good (not perfect) about updating typedefs.list by hand. But the pgindent behavior changes installed by a3e6beba6, b518ba4af, and 60f9467c3 add up to make this a relatively sizable diff.

Fix a set of typos and grammar issues across the tree

2026-04-21T05:46:22Z

This batch is similar to 462fe0ff6215 and addresses a variety of code style issues, including grammar mistakes, typos, inconsistent variable names in function declarations, and incorrect function names in comments and documentation. These fixes have accumulated on the community mailing lists since the commit mentioned above. Notably, Alexander Lakhin previously submitted a patch identifying many of the trivial typos and grammar issues that had been reported on pgsql-hackers. His patch covered a somewhat large portion of the issues addressed here, though not all of them. The documentation changes only affect HEAD.

dshash: Make it possible to suppress out of memory errors

2026-03-19T15:51:17Z

Introduce dshash_find_or_insert_extended, which is just like dshash_find_or_insert except that it takes a flags argument. Currently, the only supported flag is DSHASH_INSERT_NO_OOM, but I have chosen to use an integer rather than a boolean in case we end up with more flags in the future.

Remove #include where not needed

Liujinyang reported the one in binaryheap.c, I then found and analyzed the rest. For future patches, we require git archaelogical analysis before we accept patches of this nature.

Use palloc_object() and palloc_array() in backend code

2025-12-09T22:36:46Z

The idea is to encourage more the use of these new routines across the tree, as these offer stronger type safety guarantees than palloc(). This batch of changes includes most of the trivial changes suggested by the author for src/backend/. A total of 334 files are updated here. Among these files, 48 of them have their build change slightly; these are caused by line number changes as the new allocation formulas are simpler, shaving around 100 lines of code in total. Similar work has been done in 0c3c5c3b06a3 and 31d3847a37be. Author: David Geier Discussion: https://postgr.es/m/ad0748d4-3080-436e-b0bc-ac8f86a3466a@gmail.com
