For some strange reason, using an OID in a WHERE clause no longer works in 7.0.2. It did in 6.5.3 Here is an example psql session: ome=# create table foo (bar integer); CREATE ome=# insert into foo values (123); INSERT 29225 1 ome=# select bar from foo where oid=29225; ERROR: getattproperties: no attribute tuple 29216 -2 ome=# select oid,bar from foo; oid | bar -------+----- 29225 | 123 (1 row) This is broken in psql, Pg.pm, and PsqlODBC. The error in the ODBC driver essentially breaks Excel/MS Query access to PostgreSQL. It is possible to bypass the error by issuing a select statement directly from MS Query - the GUI tool from Excel no longer works, though. This is a long-winded way of saying that PsqlODBC actually works with 7.0.2 - except for this error. The number after the tuple in the error seems to be table-specific - it remains the same whatever oid you are querying - even a non-existing one. I submitted a bug report to the database also - wasn't sure of the preferred method. Sorry if you are getting a duplicate.
