Today's activity is small in volume but consistent in spirit: this is maintenance work aimed at making Postgres safer and more correct, not new features.
The most forward-looking change is commit 51c43a5, which continues a broader effort to move the codebase onto safer memory allocation functions. These newer routines, with names like "palloc object" and "palloc array," add type safety and guard against size overflow errors, particularly in array handling. This…
The other two commits are targeted bug fixes, both backpatched through version 18. Commit 4fb6e9e fixes a display bug in psql, where the "describe plus" command showed incorrect output for tables set to replica identity nothing. A previous refactor swapped in the wrong macro, showing "default" instead. It's a small…
Commit 803583c addresses an ASAN-detected failure in GUC file parsing, the configuration file reader. The bug involved a scanner state value that could be indeterminate if a flex error triggered cleanup before proper initialization. The fix makes that state volatile and adds a null check in buffer creation for a…
What's next: none of these are…
