Dear community.
I would like to ask a question regarding the below error occurred when
using psql client.
My environment is postgresql 12.3 docker container.
https://hub.docker.com/layers/postgres/library/postgres/12.3/images/sha256-23839ca029051ca19072dc7f40b252ae8cbcd7ef632f7b8e2da09ba3abc60214?context=explore
###
psql: error: could not connect to server: FATAL remaining connection slots
are reserved for non-replication superuser connections
###
It seems that this is caused by unused psql client sessions. Which was
caused by closing the terminal without exiting the psql session correctly.
###
postgres=# select usename,state,client_port from pg_stat_activity;
usename | state | client_port
----------+--------+-------------
| |
postgres | |
catseye | idle | -1
catseye | idle | 36718
catseye | idle | -1
catseye | idle | 52960
catseye | idle | 40854
...
###
I have tried setting *idle_in_transaction_session_timeout* , however,
this does not delete idle sessions.
Would there be any expiry settings to delete client idle sessions
automatically ?
My apology if this question was asked before but I appreciate it if someone
gives me advice.
Best Regards,
Yu Watanabe
