use declare/fetch

We're experimenting with the "use declare/fetch" setting in our MS
Access/DAO - PG 8.1 environment. We're using the psqlODBC snapshot
driver version, 8.02.01.03.

However, we're experiencing a problem. With the "use declare/fetch"
setting on we get an error on the (cache size - 49)th call to a dao
recordset's MoveNext method. So with our current cache size setting of
500, the 451st call to MoveNext generates an ODBC error. With the cache
size set to 100, the 51st call to MoveNext fails. See below for the
relevant COMM log entries.

We have tried various arguments to OpenRecordset to no
avail(dbOpenDynaset, dbOpenSnapshot, etc.). I'm guessing there's a
setting somewhere that we're missing that needs to be set in addition.

Again, thanks in advance for your attention...

PS. Is it still true that the SQLExtendedFetch calls, bookmarks,
movelast, etc., are not supported with the "use declare/fetch" setting?
