 *   DESCRIPTION
 *	Definition of the system "platter map" relation, pg_plmap.
 *	This relation provides a map of the data that appear on a
 *	Sony WORM optical platter.  If you don't have a Sony WORM
 *	jukebox, this relation won't be of any use to you, but it
 *	will still be created by initdb.
 *
 *	The genbki.sh script reads this file and generates .bki
 *	information from the DATA() statements.
