Hello,
 
the very same server instance / database that caused problems because of high OIDs for the ANSI version of psqlODBC is still (?) causing problems for the Unicode version ( tested with v9.02.01.00 ):
http://www.postgresql.org/message-id/20110103141602.204670@gmx.net
 
OIDs get clamped at 2147483647 -no problem with the ANSI version.
 
Could you check this, please?
 
Thank you very much!
 
Peter
