Subject: 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.
This is for sure MsAcess problem, and not a bug of PostgreSQL.
The indexes are recognized an filtering is fast.
Trying to open more than one “big table” will result in MS-ACCESS “Out of memory”.
Sounds like msAccess fetches all rows and put them into memory which is weird and unwise. Not a bug of PostgreSQL
Best regards
