+| pgbouncer.ignore_startup_parameters | Comma-separated list of parameters that PgBouncer can ignore. For example, you can let PgBouncer ignore `extra_float_digits` parameter. Some parameters are allowed, all others raise error. This is needed to tolerate overenthusiastic JDBC wanting to unconditionally set 'extra_float_digits=2' in startup packet. Use this if the library you use report errors such as `pq: unsupported startup parameter: extra_float_digits`. |   |
 | pgbouncer.query_wait_timeout | Maximum time (in seconds) queries are allowed to spend waiting for execution. If the query is not assigned to a server during that time, the client is disconnected. | 120s |
 | pgBouncer.stats_users | Optional. Set this parameter value to the name of an existing user, to be able to log in to the special PgBouncer statistics database (named “PgBouncer”).    |      |
