Back to “log LSN on DROP TABLE”
Fix correctness and coverage of recovery landmarks for destructive DDL.
active work
view all →Log the correct commit-record LSN for DROP TABLE and related destructive operations to make PITR recovery less guessy.
Keep logical slots usable on a standby fed by WAL archives by pausing and safely resuming recovery around conflicts.
Partial materialized-view refresh
needs reviewAdd WHERE support to REFRESH MATERIALIZED VIEW with explicit concurrency semantics.
Whole-WAL-record compression
blockedCompress or batch larger WAL records, originating in B-tree build experiments.
Custom protocol command tags
explorationNegotiate custom command-completion tags through a _pq_ protocol capability.
