Expand Up @@ -153,3 +153,16 @@ reporting are still accounted for by postgres in `pg_stat_get_db_xact_commit()`
and `pg_stat_get_db_xact_commit()`. Therefore `pg_activity` will display a non
zero TPS even with no activity on the database, and/or no activity displayed on
screen.

**How can I specify a password for authentication ?**

pg_activity uses libpq to access to PostgreSQL therefore all the traditional
methods are available.

You can pass the password for the database connection in a password file.
Information can also be given via PostgreSQL's environment variables
(PGPASSFILE or PGPASSWORD) or via the connection string parameters.

The password file is preferred since it's more secure (security is deferred to
the OS). Please avoid password in connection strings at all cost.
