  10) What is elog()?
   elog() is used to send messages to the front-end, and optionally
   terminate the current query being processed. The first parameter is an
   elog level of NOTICE, DEBUG, ERROR, or FATAL. NOTICE prints on the
   user's terminal and the postmaster logs. DEBUG prints only in the
   postmaster logs. ERROR prints in both places, and terminates the
   current query, never returning from the call. FATAL terminates the
   backend process. The remaining parameters of elog are a printf-style
   set of parameters to print.
