Postgresql15 crash with :FATAL: could not open shared memory segment "/PostgreSQL.0000000": No such file or directory

Hi,
Can you please look into this:
Postgres version 15 randomly crash with the following error : FATAL: could not open shared memory segment "/PostgreSQL.2771626404": No such file or directory

After testing I found out that when shared memory is removed on:

1-PostgreSQL 12, 13,14: no impact, the server perform as normal.
2-PostgreSQL 15: postgresql server crash and no user is able to login to the DB. Any attempt to login you will get the above error.

Regards,
Emile
