Robert Haas 26981d2927 Don't send protocol messages to a shm_mq that no longer exists. ... Commit 2bd9e412f9 introduced a mechanism for relaying protocol messages from a background worker to another backend via a shm_mq. However, there was no provision for shutting down the communication channel. Therefore, a protocol message sent late in the shutdown sequence, such as a DEBUG message resulting from cranking up log_min_messages, could crash the server. To fix, install an on_dsm_detach callback that disables sending messages to the shm_mq when the associated DSM is detached.		2015-10-16 09:49:08 -04:00
