Re: stack depth - Mailing list pgsql-general

a little update,

I've tried the instructions at this URL:
https://ma.ttias.be/increase-open-files-limit-in-mariadb-on-centos-7-with-systemd/

I either get the same errors appear when I run systemctl daemon-reload;
systemctl restart postgresql-9.4

Or


I have tried moving the 'LimitSTACK=12288' to other sections of the
service file, I see this in /var/log/messages

I've also tried what it says in the service file -

# It's not recommended to modify this file in-place, because it will be
# overwritten during package upgrades.  If you want to customize, the
# best way is to create a file "/etc/systemd/system/postgresql-9.4.service",
# containing
#       .include /lib/systemd/system/postgresql-9.4.service
#       ...make your changes here...
# For more info about custom unit files, see
#

But nothing works as yet!
