 *	  definition of the "shared description" system catalog
 *	  (pg_shdescription)
 *
 * Because the contents of this table are taken from the *.dat files
 * of other catalogs, there is no pg_shdescription.dat file. The initial
 * contents are assembled by genbki.pl and loaded during initdb.
 *
 * NOTE: an object is identified by the OID of the row that primarily
 * defines the object, plus the OID of the table that that row appears in.
 * For example, a database is identified by the OID of its pg_database row
 * plus the pg_class OID of table pg_database.  This allows unique
 * identification of objects without assuming that OIDs are unique
 * across tables.
