+ * 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.
