Export a column in a view without "announcing" it?

I'm fairly certain there is currently no way to do this, but it would make life a bit easier for me right now if there were, so I guess I'm going to ask it anyway, just in case:

Is there any way to expose a column in a view without "announcing" the fact that it is there? Specifically, in order to support updatable cursors on views (faked ones, using the ODBC driver), it is necessary to include the underlying table's OID and CTID columns in the view; but the client software I am trying to use then chokes on there being a column named OID (which is present, but hidden, if I use a table). So basically I would like to do:

CREATE VIEW aView AS
SELECT x, y, OID, CTID, z, t, ... FROM aTable WHERE condition_met WITHOUT ANNOUNCING OID, CTID



or some such, so that if a query requesting OID or CTID is made, it will be there, while if a client asks for a list of columns, OID and CTID are not given?


Also: with respect to the "fake" updatable cursors: if the client program attempts an INSERT operation and does not provide values for OID and CTID, am I correct in assuming that the database will correctly fill in these columns automatically?

Thank you!
