PostgreSQL inside a FreeBSD Jail

Fri, 09/20/2024 - 23:55 by Daniel Morante

PostgreSQL requires access to shared memory otherwise it refuses to start.

This error will almost always happen if you try to run PostgreSQL inside a jail

FATAL:  could not create shared memory segment: Function not implemented
DETAIL:  Failed system call was shmget(key=43714, size=56, 03600).
child process exited with exit code 1
Add this to your /etc/jail.conf or were you have your jail defined. 
allow.sysvipc;

Then restart your jail and continue with setup
