>In general, no. That's because resultset columns can be "entangled" in more complex way than "column a of table b".
Actually, this *is* defined at the protocol level:
From the RowDescription message at
http://developer.postgresql.org/pgdocs/postgres/protocol-message-formats.html
:
...
Then, for each field, there is the following:
String
The field name.
Int32
If the field can be identified as a column of a specific table,
the object ID of the table; otherwise zero.
...
No idea whether JDBC exposes this or whether the server actually sends
the correct oids, or if this is just part of the protocol as a
future-proofing attempt.
