Type: | bool |
Default: | off |
Context: | superuser-backend |
Restart: | false |
Causes each attempted connection to the server to be logged, as well as successful completion of both client authentication (if necessary) and authorization. Only superusers and users with the appropriate SET
privilege can change this parameter at session start, and it cannot be changed at all within a session. The default is off
.
Some client programs, like psql, attempt to connect twice while determining if a password is required, so duplicate connection received messages do not necessarily indicate a problem.
