By the errors I will assume that it should be in the [Service] section.
I couldn't find confirmation of this online...
Yes, it belongs in the [Service] section.
$ man systemd.exec

"The execution specific configuration options are configured in the
[Service], [Socket], [Mount], or [Swap] sections, depending on the unit

However, I assume that you are confused because "ulimit" in a bash shell
returns a value in KiB, but LimitSTACK and setrlimit accept a value in
bytes. That is, you've decreased the stack size to 12KiB, which is why
PostgreSQL segfaults immediately.
# cat /etc/systemd/system/postgresql.service
.include /lib/systemd/system/postgresql.service
[Service]
LimitSTACK=12582912
# grep stack /var/lib/pgsql/data/postgresql.conf
max_stack_depth = 10MB # min 100kB
# systemctl daemon-reload
# systemctl restart postgresql
