This is the final commit that adds PG17 compatibility with Citus's current capabilities. You can use Citus community, release-13.0 branch, with PG17.1. --------- Specifically, this commit: - Enables PG17 in the configure script. - Adds PG17 tests to CI using test images that have 17.1 - Fixes an upgrade test: see below for details In `citus_prepare_upgrade()`, don't drop any_value when upgrading from PG16+, because PG16+ has its own any_value function. Attempting to do so results in the error seen in [pg16-pg17 upgrade](https://github.com/citusdata/citus/actions/runs/11768444117/job/32778340003?pr=7661): ``` ERROR: cannot drop function any_value(anyelement) because it is required by the database system CONTEXT: SQL statement "DROP AGGREGATE IF EXISTS pg_catalog.any_value(anyelement)" ``` When 16 becomes the minimum supported Postgres version, the drop statements can be removed. --------- Several PG17 Compatibility commits have been merged before this final one.
