/*-------------------------------------------------------------------------
*
* pg_init_privs.h
* definition of the "initial privileges" system catalog (pg_init_privs)
*
* 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 function is identified by the OID of its pg_proc row
* plus the pg_class OID of table pg_proc. This allows unique identification
* of objects without assuming that OIDs are unique across tables.
*
* Since attributes don't have OIDs of their own, we identify an attribute
* privilege by the objoid+classoid of its parent table, plus an "objsubid"
* giving the attribute column number. "objsubid" must be zero in a privilege
* for a table itself, so that it is distinct from any column privilege.
* Currently, objsubid is unused and zero for all other kinds of objects.
*
* Because the contents of this table depend on what is done with the other
* objects in the system (and, in particular, may change due to changes in
* system_views.sql), there is no pg_init_privs.dat file. The initial contents
* are loaded near the end of initdb.
