Subject: [PATCH] PG-286: Fix deadlock.

Can't call elog() function from inside the pgsm_log as the pgss_hash
lock could be already acquired in exclusive mode, since elog() triggers
the psmg_emit_log hook, when it calls pgss_store it will try to acquire
the pgss_hash lock again, leading to a deadlock.
