You might need to add explicit type casts. Even this: SELECT levenshtein_less_equal('extensive'::TEXT, 'exhaustive'::TEXT,2::INTEGER); function levenshtein_less_equal(text, text, integer) does not exist But this works perfectly: SELECT levenshtein('extensive', 'exhaustive'); 4
Are you sure you are connecting to a 9.1 server? levenshtein_less_equal does not exist in 9.0- which would result in that error.
When you are in psql what does: SELECT version(); and \df levenshtein_less_equal show?
