You'd need to cats your numbers to text strings, but it looks like it will drop useless 0's for you. test=# SELECT trim(trailing 0 FROM '12.300'::TEXT)::NUMERIC; rtrim ------- 12.3 (1 row) ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
