I guess the threshold question for this patch is whether
pg_table_size() is a "more accurate" table size or just a different
one.  It could possible be confusing to display one value in that
column when the server is >= 9.0 and the client is >= 9.1, and a
different value when the server is < 9.0 or the client is < 9.1.

On the other hand, it's clear that there are several people in favor
of this change, so maybe we should just go ahead and do it.  Not sure.
