Matthias van de Meent 3e6fdb0aa6 Add and use [U]INT64_[HEX_]FORMAT for various [u]int64 needs (#12592) 
We didn't consistently apply these, and it wasn't consistently solved.
With this patch we should have a more consistent approach to this, and
have less issues porting changes to newer versions.

This also removes some potentially buggy casts to `long` from `uint64` -
they could've truncated the value in systems where `long` only has 32
bits.

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.
