3  * pg_shdescription.h
4  * definition of the "shared description" system catalog
5  * (pg_shdescription)
6  *
7  * Because the contents of this table are taken from the *.dat files
8  * of other catalogs, there is no pg_shdescription.dat file. The initial
9  * contents are assembled by genbki.pl and loaded during initdb.
10  *
11  * NOTE: an object is identified by the OID of the row that primarily
12  * defines the object, plus the OID of the table that that row appears in.
13  * For example, a database is identified by the OID of its pg_database row
14  * plus the pg_class OID of table pg_database. This allows unique
15  * identification of objects without assuming that OIDs are unique
16  * across tables.
