No because it's completely unrelated. The amount of shared memory
doesn't vary while the system is running and it gets removed once you
restart postgres. So it can't cause you to run out of memory (unless
you allocated a truly huge amount of memory that way, but that's bad
for other reasons). At worst it's gets stuffed into swap until you next
start postgres.
Have a nice day,
