I know we shouldn't use them; but ...
We have some apps that are using OIDS only as a unique key for updating
single records in table.
To transfer these tables to another system using pg_dump; I really only
need "WITH OIDS" on the CREATE TABLE command, not the COPY statements.
While playing with this I noticed that using the -c -o options of
pg_dump together; I get OIDS in COPY statements, but not in the CREATE
commands. Either this is a bug; or I'm missing something here...
