Hmm I thought I had but pg_depend is one that I missed.  I deleted all
refs to rows in pg_depends and was able to drop the table.

FWIW I tried to use alter table but could never get the parser to accept
$1 as a constraint name.  I used single and double quotes as well as a
lame attempt \$1.

Thanks I am breathing better.  I was about to pg_dump and restore into a
test database to see what would happen then since there was no reference
to any of the oids in the error messages found in the dump.

I can now resume climbing up the learning curve.
