The following bug has been logged on the website:
Bug reference: 16897
Logged by: Richard Crampton
Email address: rich(dot)crampton(at)gmail(dot)com
PostgreSQL version: 12.6
Operating system: client Windows 10, postgresql server Ubuntu
Description:
When connecting over a local network from Windows 10 to PostgreSQL server
(Linux version 12.6 default install) the gssencmode=prefer in libpq
connection causes a big slowdown.
With "gssencmode=prefer" connection takes 4 seconds.
With "gssencmode=disable" connection as fast as normal.
As the prefer option is the default option this causes problems in dependent
libraries such as psycopg2 for Python. First raised the bug here
https://github.com/psycopg/psycopg2/issues/1242 but I think this must be a
libpq/Postgresql bug since psycopg2 is just passing along the request.
