MS-ACCESS 2010, ODBC 12.01, Out of Memory

Win10-Client:  MS-ACCESS 2010 (32-Bit),  ODBC-Driver:  12.01

Linux-Server (1):  PostgreSQL 12.2

Linux-Server (2):  PostgreSQL  9.6

We are currently migrating from PG 9.6. to 12.x.

We’ve created System-DSNs (PostgreSQL Unicode) with [Defaults] for both Server.

In MS-ACCESS our biggest Server-Tables (>14.000.000 Rows) can be opened (on both Servers).

But it takes a lot of time and uses a lot of memory - more than 450MB on the client and some GB on the server.

The indexes are recognized an filtering is fast.

Trying to open more than one “big table” will result in MS-ACCESS “Out of memory”.

Best regards
