   * pg_shdescription.h
   *	  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.
