PostgreSQL: Cleaning Up the Codebase's Foundations
Three commits landed today focused on code correctness and modernization rather than features—one raising the compiler baseline by adopting a C11 standard, one tightening internal API consistency, and one closing a test gap in crash recovery logic.

Good morning. It's July 14th, 2026, and this is your PostgreSQL briefing.
Today's activity is small but meaningful: three commits, all centered on making the codebase more correct and more maintainable, not on new features.
The headline change comes from Peter Eisentraut, commit d15a6bc, which replaces a GCC-specific compiler builtin with the standard C11 feature called "Generic." This affects internal macros used for type-safety checks and for stripping constness or volatility from variables. The practical upshot: Postgres now relies…
The second theme is API hygiene. In commit 7b87f08, also from Eisentraut, the block reference table API was updated to use size_t and ssize_t instead of plain int for lengths. This is described as unlikely to cause a practical bug today, but it makes the API's contract consistent from top to bottom—the kind of…
Third, Michael Paquier added a recovery test, commit 8f71f64, covering a previously untested scenario: startup when a backup label's checkpoint and redo log locations span different segments, and the redo segment is missing. This path was complex and uncovered before—now there's a regression test guarding it,…
What's next: watch for downstream…
