I am not following here. If an extension is dropped, so are its
dependencies. See that for example:
=# create extension pg_trgm;
CREATE EXTENSION
Time: 27.978 ms
=# \dx+ pg_trgm
Objects in extension "pg_trgm"
Object Description
--------------------------------------------------------------------------------------------------
function
gin_extract_query_trgm(text,internal,smallint,internal,internal,internal,internal)
function gin_extract_value_trgm(text,internal)
[... lots of objects, including functions ...]
=# DROP EXTENSION pg_trgm;
DROP EXTENSION
=# \df gin_extract_query_trgm
