Missing tables in tree

Love pgAdmin, but I've run into a problem since moving my server from my
internal network to one hanging off of the Internet directly.  On the
client, I'm running pgAdmin 1.6.0 with psqlODBC 7.3.100.  Server-side, it's
PostgreSQL 7.3.4 on a Debian Woody box.

Previously, I would connect to the server, see a list of the databases, then
when I clicked on one and expanded it in the tree, I would see all manner of
cool things including Tables.  No longer.  I see only Casts, Languages, and
Schemas.  The logged-in user is defined as:

CREATE USER username WITH SYSID 103 CREATEDB CREATEUSER VALID UNTIL
'2006-01-17 00:00:00';

I've tried about a dozen Google queries, but I haven't found the magic one
yet.

I don't mean to complain, but Casts, Languages, and Schemas are not nearly
as useful to me as -- say -- Tables, Indexes, and Sequences.  Any and all
help, pointers, or even sympathy will be greatly appreciated.

Please cc me on replies, since I'm not on the list.  Thanks!
