Tristan Partin da79cc5eee Add neon.extension_server_{connect,request}_timeout (#10801)
Instead of hardcoding the request timeout, let's make it configurable as
a PGC_SUSET GUC.

Additionally, add a connect timeout GUC. Although the extension server
runs on the compute, it is always best to keep operations from hanging.
Better to present a timeout error to the user than a stuck backend.

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.
