[BUG] postgres function ownership isn't determined correctly

[nicholasmhughes]

Description
the query that determines the owner of a function seems to be broken

[ERROR   ] Command '/usr/bin/psql' failed with return code: 1
[ERROR   ] stderr: ERROR:  column "rolname" does not exist
LINE 1: COPY (SELECT rolname AS name FROM pg_catalog.pg_proc p JOIN ...
                     ^
HINT:  Perhaps you meant to reference the column "p.proname".
[ERROR   ] retcode: 1
[ERROR   ] Error connecting to Postgresql server
