PostgreSQL: Hardening the Data Checksum Rollout
Today's commits center on tightening up the online data checksum feature with two separate bug fixes, alongside a scattering of correctness and code-quality patches across buffer management, vacuum, and code style. Most fixes are backpatched through version 19, signaling active stabilization of recent features.

Good morning. It's July 11th, and today's PostgreSQL commit activity tells a clear story: the online data checksum feature is getting stress-tested and patched.
Two commits from Fujii Masao target this directly. Commit e981025 fixes progress counter reporting in pg_stat_progress_data_checksums—counters were showing zero instead of null, which could mislead anyone monitoring a checksum rollout in progress. Commit 97a18c2 goes deeper, fixing two edge cases: temporary views…
A second theme is defensive correctness in long-standing code paths. Andres Freund's commit c787c95 fixes an order-of-operations bug in buffer header locking, where a specific error flag could be cleared when it shouldn't be—subtle, but the kind of bug that erodes trust in error reporting under concurrency. Melanie…
Rounding things out, Peter Eisentraut landed two cleanup commits, fixing loop variable types across several modules to avoid signed-versus-unsigned mismatches—no functional impact expected, but it reduces warning noise and fragility for future changes.
What to remember: if you're testing or deploying online data checksums, today's fixes close real gaps in progress reporting and completion…
That's the…
