Обсуждение: error connecting to pgbouncer admin console

I did a pgbouncer configuration using the following ini file:



[databases]
* = host=localhost port=5433 auth_user=pgbouncer
[users]
[pgbouncer]
logfile = /pgdata/pcl_l002/pgbouncer/pgbouncer_pcl_l002.log
pidfile = /pgdata/pcl_l002/pgbouncer/pgbouncer_pcl_l002.pid
listen_addr = *
listen_port = 6433
auth_type = hba
auth_file = /pgdata/pcl_l002/pgbouncer/userlist_pcl_l002.txt
auth_hba_file = /pgdata/pcl_l002/pg_hba.conf
auth_user = pgbouncer
auth_query = SELECT * FROM pgbouncer.get_auth($1)
admin_users = monitor
stats_users = stats, monitor
max_client_conn = 500
default_pool_size = 20
log_connections = 1
log_disconnections = 1
log_pooler_errors = 1



Everything is fine as long as I connect to any database within the postgres cluster as any user.



As soon as I try to connect to the pgbouncer admin console I get the following error:

$ psql -h localhost -p 6433 -U monitor pgbouncer
psql: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.

$ psql -h localhost -p 6433 -U stats pgbouncer
psql: server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.



There is always the same error within the pgbouncer logfile:
...

PgBouncer 1.16.1

Any idea?



Thanks, Markus

Using the name "pgbouncer" for auth_user is buggy.  Try using a 
different name.

Simply a bug.
