Very high memory utilization in Wondows 10 and Ubuntu with OBDBC Driver 13.1 and 13.2

Hello,

we came across a problem with the PostgreSQL ODBC driver version 13.1 and 13.2.
It uses all available system memory, which is about 22GB on my system.

This problem occurred after updating from version 13.0 to 13.2 and can also be reproduced with version 13.1.
The highest amount of used memory occurs during read operations on a database which contains about 50 MB of data.
The version of the PostgreSQL database seem to be not of interest, reproduced the problem with all version from13.0 up to 14.2.

We also found that the setting the following option solves that problem in our case.



We would like to know if this is a bug introduced in 13.1 or if we do something wrong.
If you need for information please get in touch with me.

Best regards,
Maurice Duvigneau
