postgresql-timescaledb: updated to 2.12.2

2.12.2

This release contains bug fixes since the 2.12.1 release.
We recommend that you upgrade at the next available opportunity.

Bugfixes

* Align gapfill bucket generation with time_bucket
* Ensure fixed_schedule field is populated
* Fix EXPLAIN ANALYZE for compressed DML

2.12.1

This release contains bug fixes since the 2.12.0 release.
We recommend that you upgrade at the next available opportunity.

Bugfixes

* Fix planner distributed table count
* Avoid decompressing batches using an empty slot
* Fix concurrency errors in OSM API
* do not throw an error when deprecation GUC cannot be read

2.12.0

This release contains performance improvements for compressed hypertables
and continuous aggregates and bug fixes since the 2.11.2 release.
We recommend that you upgrade at the next available opportunity.

This release moves all internal functions from the _timescaleb_internal
schema into the _timescaledb_functions schema. This separates code from
internal data objects and improves security by allowing more restrictive
permissions for the code schema. If you are calling any of those internal
functions you should adjust your code as soon as possible. This version
also includes a compatibility layer that allows calling them in the old
location but that layer will be removed in 2.14.0.

PostgreSQL 16 support will be added with a following TimescaleDB release.
