Summary: "Requested conversion is not supported" when trying to query information_schema.tables on SQL
Initial Comment:
I got this error:
Could not get the current row value of column '[MSDASQL].table_catalog' from the OLE DB provider 'MSDASQL'.
[OLE/DB provider returned message: Requested conversion is not supported.]
OLE DB error trace [OLE/DB Provider 'MSDASQL' IRowset::GetData returned 0x80040e1d].
when I am trying to execute the following queries on SQL Query Analyzer:
a) SELECT * FROM OPENQUERY(my_linked_server,'SELECT * FROM information_schema.tables')
b) SELECT * FROM OPENQUERY(ufa_selfserve_PGSQL80,'SELECT * FROM pg_catalog.pg_constraint')
my_linked_server is defined as a SQL linked server using Microsoft OLE DB Provider (MSADSQL).
However, the following error result no error:
SELECT * FROM OPENQUERY(ufa_selfserve_PGSQL80,'SELECT * FROM pg_catalog.pg_depend')
I have tried both psqlodbc-08_01_0102 and psqlodbc-8_01_0106 but they behave the same.
Any help is appreciated.
Thanks.

Please attach mylog output as it's is more useful for bug hunting (it's much larger so feel free to compress it).
