I'd like to take another look at Range Types and whether part of it

First of all, what are the advantages to being in core?
it should be supported by FOREACH statement in PL/pgSQL
Yes, absolutely. I know this feature is loved in Perl. But this usage would
only work for a more limited range of data types, namely those over which one
can build a sequence generator, such as integers, because they have a
next-value/prev-value function defined. In other words, while range types in
general would work for any ordered type, FOREACH would only work for the subset
of those that are ordinal types. -- Darren Duncan
