Yes, I see now in my backups that 6.5.1 was truncating at 31 characters but
just wasn't telling me. I wasn't aware if the limit. So it is nice to have
the notice, but perhaps should only show up once (e.g. when the table is
initially created). That way, once you've been advised of the truncation, it
won't annoy you any longer.

I tried changing NAMEDATALEN in the postgres_ext.h to 52. Everything compiled
and installed fine, but the initdb failed. Maybe there is more to it than
just changing that one constant. Anyway, I've gone back to the original
NAMEDATALEN = 32 and will just rename my field to something smaller than 31
chars.
