I get errors claiming the functions are unknown, but when I try running CREATE EXTENSION tablefunc, I am told that its methods already exist. This looks like a search_path problem. You could try "\dx+ tablefunc" to see which schema its functions are in, then adjust your search_path to include that, or else schema-qualify the function names. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
