It seems that I'm the only one who objects to optional OIDs
as usual:-).
IMHO OIDs are not for system but for users.
OIDs have lived in PostgreSQL world from the first(???).
Isn't it sufficiently long for users to believe that OIDs
are unique (at least per table) ?
As I mentioned already I'm implementing updatable cursors
in ODBC and have half done it. If OIDs would be optional
my trial loses its validity but I would never try another
implementation.
