Improvements have already been made in this are for the 8.2 driver (which
can be used against older database versions). It currently reports
10485760 as the precision for bpchar.
The complication on your part is that bpchar is kind of an internal type
name and you've already noticed that you can't say CREATE TABLE t (a
bpchar(5)). The grammar only supports the precision attribute on the
external spelling of the type name, char or character. I'm not sure how
the pg jdbc driver can help you know this.
