Hi,

>See the section about sslcompression in https://www.postgresql.org/docs/9.2/libpq-connect.html. It should be your answer.

I added

sslcompression=1

to psqlodbc connection string but log file shows that connection is still uncompressed:

LOG: connection authorized: user=me database=mydb SSL enabled (protocol=TLSv1.3, cipher=TLS_AES_256_GCM_SHA384, bits=256, compression=off)

Maybe because according to TLSv1.3 standard, compression is no more allowed or psqlodbc does not pass it to pglib.

How to compress ?

Andrus.
