updated extensions for postgres 18

Hey everyone, this is my first email to this list, so feel free to point me
out to the proper place.

Some packages are missing for postgres 18:
* pg_qualstats: https://github.com/powa-team/pg_qualstats/releases/tag/2.1.2
* pglogical: https://github.com/2ndQuadrant/pglogical/releases/tag/REL2_4_6
* pgaudit: https://github.com/pgaudit/pgaudit/releases/tag/18.0
* postgres-hll:
https://github.com/citusdata/postgresql-hll/releases/tag/v2.18
* pldebuger: https://github.com/EnterpriseDB/pldebugger/releases/tag/v1.9

Where can I patch the build files to add the new versions?
