|
* pg_shdescription.h
|
|
* definition of the system "shared description" relation
|
|
* (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.
