Modified files:
doc/src/sgml : datatype.sgml
src/backend/parser: analyze.c gram.y
src/backend/utils/adt: format_type.c
Log message:
Tweak parser so that there is a defined representation for datatypes
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.
