Does that mean the column statistics will only be collected when there's an index on the table/column? No; ANALYZE collects stats on plain columns automatically. The point is that your query is not on the plain column searchfield1, it is on lower(searchfield1). The planner cannot make a reasonable estimate for "something LIKE constant-pattern" unless it can find statistics that are specifically for the "something" value. 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
