Tried to compile 3 large programs at one time and the CPU overheated, shutting down the server. Now when I try to start postgres-9.5.4 (as the superuser, postgres) I get this result: postgres@salmo:~$ postgres -D /var/lib/pgsql/9.5/data/ & [1] 14544 postgres@salmo:~$ FATAL: could not open shared memory segment "/PostgreSQL.1804289383": Permission denied Not before encountering this problem I've no idea where to look to see how to fix it. Please advise. TIA, Rich -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
