It should take syncrep flush_lsn into account because WAL before it on endpoint restart is lost, which makes replication miss some data if slot had already been advanced too far. This commit adds test reproducing the issue and bumps vendor/postgres to commit with the actual fix.
neon extension consists of several parts:
shared preload library neon.so
-
implements storage manager API and network communications with remote page server.
-
walproposer: implements broadcast protocol between postgres and WAL safekeepers.
-
control plane connector: Captures updates to roles/databases using ProcessUtility_hook and sends them to the control ProcessUtility_hook.
-
remote extension server: Request compute_ctl to download extension files.
-
file_cache: Local file cache is used to temporary store relations pages in local file system for better performance.
-
relsize_cache: Relation size cache for better neon performance.
SQL functions in neon--*.sql
