Amit Kapila and Vignesh C landed a multi-part fix, commit b8-d9-c-f-5, addressing a stale subscription cache that let a sync worker keep running after it should have…
A second theme is subscription security and correctness. Fujii Masao's commit 1-c-9-c-358 fixes a case where changing a subscription's owner could silently produce an invalid connection string, one that didn't meet password requirements, without any validation at the time of the change. That's now checked…
A third theme is test infrastructure for concurrency edge cases. Peter Geoghegan added three separate test suites this week: one for B-tree backward scan recovery during concurrent page splits and deletions, commit e-3-9-5-f-b-d; one for predicate locking behavior on completely empty indexes, commit 6-2-c-0-5-d-6;…
