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.
