Thread: pgsql-server: Revert ill-conceived patch that made elog(FATAL) the same

Log Message:
-----------
Revert ill-conceived patch that made elog(FATAL) the same as elog(ERROR)
followed by seeing EOF from client.  If we want a safe session-kill
capability we will need to write one, not break our error handling
mechanism.
