Hi,
The oid column is classed as a system column, and as such is only
visible with 'View System Objects' turned on. You should not use this
column in your databases unless you have a very specific reason - one
very good reason not to use them is that OIDs are not necessarily
included in database dumps, therefore referential integrity might be
broken if you restore such a dump and had used the OID column in foreign
keys. There are also potential problems with OID-wraparound on large
databases.
Instead, I would suggest using a serial column as your PK etc. in all
your tables.
