List databases using ODBC through OLE DB

Hi -

I am attempting to build a connection dialog for Postgres using the
ODBC driver through the Windows OLE DB interface. We have done this
for a number of other engines (including MySQL) and I am trying to
get it up and running for Postgres.

The problem I am having is that we are unable to get a list of
databases from the server once we are connected. The request fails
to complete when requesting either DBSCHEMA_CATALOGS or
DBSCHEMA_SCHEMATA from the IID_IDBSchemaRowset::GetRowset API.

Does anyone know the correct incantation to use here?

TIA,
