- PGREALM
-
- PGREALM sets the Kerberos realm to use with
- PostgreSQL, if it is different from the
- local realm. If PGREALM is set,
- libpq applications will attempt
- authentication with servers for this realm and use separate ticket
- files to avoid conflicts with local ticket files. This
- environment variable is only used if GSSAPI authentication is
- selected by the server.
