OBBO67 82cbab7512 Switch reqlsns[0].request_lsn to arrow operator in neon_read_at_lsnv() (#10620) (#10687)
## Problem

Currently the following line below uses array subscript notation which
is confusing since `reqlsns` is not an array but just a pointer to a
struct.

```
XLogWaitForReplayOf(reqlsns[0].request_lsn);
```

## Summary of changes

Switch from array subscript notation to arrow operator to improve
readability of code.

Close #10620.

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.
