pgadmin3 doesn't list oid in columns

[dima Q <dimaqq(at)gmail(dot)com>]

Pgadmin3 doesn't seem to think of oid as a column in a table created
"with oids".

The consequences of this are:
oid cannot be used when making constraints PK, FK, UNIQUE, etc in
table modification dialog
oid cannot be used when creating constraints in the constraint dialog
oid cannot be used when making indices with pgadmin3

I created oid-related constraints, indices etc. by hand and they can
be viewed by pgadmin3 though.

Is this a misfeature or you disabled such functionality on purpose
because it can be seen as "bad style" in postresql?
