Hello, I am running 8.4 with various contrib modules (hstore-new, pg_trgm, fuzzystrmatch). If I wanted to upgrade to 9.1, can I / would I have to uninstall the contrib modules? Are there any incompatibilities between the contrib and corresponding 9.1 functions? -- Best Regards, Tarlika Elisabeth Schmitz -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
