Hi, Because gitlab next major upgrade needs a newer version of postgresql we have to upgrade it. What we have: postgres=> select version(); version --------------------------------------------------------------------- ----------------------------------------- PostgreSQL 14.6 on aarch64-unknown-linux-gnu, compiled by gcc (GCC) 7.3.1 20180712 (Red Hat 7.3.1-6), 64-bit (1 row) and List of installed extensions Name | Version | Schema | Description ------------+---------+------------+----------------------------------- -------------------------------- btree_gist | 1.6 | public | support for indexing common datatypes in GiST pg_trgm | 1.6 | public | text similarity measurement and index searching based on trigrams plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language (3 rows) now normally I would probably do 'upgrade' in the aws-console but on aws rds PG 15 has a newer btree_gist version (1.7) Are there any caveats concerning those extensions? best regards, Alexander.
