I doubt it: the data you selected from information_schema.columns is
quite independent of the column types, so even if there were such a
problem in DBD::pg it could hardly manifest in this way.
What I'm wondering about is if you are connecting to the same database
in both the DBD::pg test program and the manual psql try. Another
possibility is multiple tables of the same name in different schemas,
perhaps compounded by different ownerships --- I think the
information_schema hides info about tables you don't have any access
privileges for. Is the test program connecting as the same database
user you were using manually?
