I'm using default 'postgres' user on managed Azure PostgreSQL v13 which has admin rights.
Yesterday it was saying something like "superuser access required to ALTER extension". I was able to DROP+CREATE extension, but not ALTER it. It required only super-user
DROP EXTENSION btree_gin;
CREATE EXTENSION IF NOT EXISTS btree_gin WITH SCHEMA shared_extensions;
which looked like it works, but I was not able to drop some extensions as they were in use.
I tried it today and for some reason it looks like it's working:
public> ALTER EXTENSION btree_gin SET SCHEMA extensions
[2022-08-24 07:38:51] completed in 73 ms
Do you think there could be some change which prevented this change yesterday but now it works?
