I have postgresql 9.4 on a cluster, hardware based. I need to be able to see which users are connecting to which database and when to be in compliance with our security policies.
I have set the following in the postgresql.conf and did a pg_ctl reload:
log_connections = on log_line_prefix = '%t [%p]:[%u]:[%h]-[%d] [%1-1]'
should work, can you check if those settings are in effect?
select name, setting from pg_settings where name in ('log_connections','log_line_prefix');
