Changelog 2022 10 25

Compute: Added support for Postgres 15.0 and its Postgres extensions. For information about supported extensions, see Available Postgres extensions.
Compute: Disabled the wal_log_hints parameter, which is the default Postgres setting. The Pageserver-related issue that required enabling wal_log_hints has been addressed, and enabling wal_log_hints is no longer necessary.
Pageserver: Added a timeline state field to the TimelineInfo struct that is returned by the timelines internal management API endpoint. Timeline state information improves observability and communication between Pageserver modules.
