I've tried various settings, upgraded to psqlodbc 8.02.0200, looked into
the source (info.c, retry_public_schema label) and there's a query which
gets the columns (select n.nspname, c.relname, a.attname, a.atttypid
(...)), I now can even see it in logs but there's still this additional
select before. I think it's not psqlodbc problem, because when I
issue my queries directly from isql from unixodbc everything seems normal
- I get this additional select only when quering from Oracle using
@my_server. Therefore, I think it is Oracle's fault and try to move this
topic to Metalink. Thank you again.
