Arseny Sher db53f98725 neon walsender_hooks: take basebackup LSN directly. (#9263) 
NeonWALReader needs to know LSN before which WAL is not available
locally, that is, basebackup LSN. Previously it was taken from
WalpropShmemState, but that's racy, as walproposer sets its there only
after successfull election. Get it directly with GetRedoStartLsn.

Should fix flakiness of
test_ondemand_wal_download_in_replication_slot_funcs etc.

README.md

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

Utility functions to expose neon specific information to user and metrics collection. This extension is created in all databases in the cluster by default.
