bpchar, bit, numeric with typmod -1. Alter format_type so that this representation is printed when the typmod is -1. This ensures that tables having such columns can be pg_dump'd and reloaded correctly. Also, remove the rather useless and non-SQL-compliant default precision and scale for type NUMERIC. A numeric column declared as such (with no precision/scale) will now have typmod -1 which means that numeric values of any precision/scale can be stored in it, without conversion to a uniform scale. This seems significantly more useful than the former behavior. Part of response to bug #513. |
