No pg-bouncer or connection pooling.
ps -elf | grep postgres | grep idle | wc -l ==> 61
and BTW: Running, say 500 one command psql in parallel will have the same
affect..
Hmm. In psql on the cluster in question what does below return?:
show max_connections;

Hi,
Will appreciate a hint here.
Running on a big and stressed AIX platform and receiving lots of "CDTFATAL: sorry,
too many clients already"
and transient difficulty to log in.
Happens on all PG versions (Tested 9.5,10.4,11.5)
Big installation: max_connections is 1200, shared_buffers is 2GB
But .. select count(*) from pg_stat_activity is only 66.
Thanks
Danny
Lots of idle, kept-alive clients? Do you have a connection pooler (e.g.
pg-bouncer)?
