"oid" as a special system column and the WITH OIDS option when creating
tables are being removed in pg12 (having been deprecated for something
like 12 years now), you might want to start thinking about alternatives.
PegoraroF10> So, there is a way to get OID on transition tables ?
Well, arguably it is an oversight in the implementation of transition
tables that they were not added to the various places in the parser that
treat "oid" as a system column name. However, I not sure that you'll get
any agreement to fix that in light of the demise of "oid" as mentioned
above. (Not least because backpatching it could be dangerous in that it
could break queries that now work, by making "oid" an ambiguous column
reference.)
I tried various workarounds, but they were defeated by the fact that
evaluation of a whole-row Var does not copy the oid value (if any).
(I'm not sure if this ever really worked, so calling it a bug may be a
bit of a stretch.)
