*
* 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.
