Hmm, I seem to be getting negative values for tables that were created
without a maximum char length. Is (was) it legal postgres syntax to
say something like
create table foo (mytext varchar);
without a maximum length constraint? psql (or perhaps the Perl
interface) let me create such tables under 6.5.3 and they've worked
fine, up until this pg_dump. Would it be safe to simply edit the
dumped file, change the negative values to something reasonable and
reload the DB?
Thank you for your assistance.
