Subject: DBI::InterfaceError: Unsupported Type (typeid=1034)

While experimenting with DBI and my PostgreSQL database I
stumbled upon this:

irb(main):003:0> aResult = aConnection.select_all("select * from pg_class")
DBI::InterfaceError: Unsupported Type (typeid=1034)
	from /usr/local/stow/ruby/lib/ruby/site_ruby/1.6/DBD/Pg/Pg.rb:265:in `convert'

Looks like DBD/Pg has some problems with the table.
