This allows unique identification10 * of objects without assuming that OIDs are unique across tables.11 *12 * Since attributes don't have OIDs of their own, we identify an attribute13 * privilege by the objoid+classoid of its parent table, plus an "objsubid"14 * giving the attribute column number.  "objsubid" must be zero in a privilege15 * for a table itself, so that it is distinct from any column privilege.16 * Currently, objsubid is unused and zero for all other kinds of objects.17 *18 * Because the contents of this table depend on what is done with the other19 * objects in the system (and, in particular, may change due to changes in20 * system_views.sql), there is no pg_init_privs.dat file. The initial contents21 * are loaded near the end of initdb.22 *23 *24 * Portions Copyright (c) 1996-2023, PostgreSQL Global Development Group25 * Portions Copyright (c) 1994, Regents of the University of California26 *27 * src/include/catalog/pg_init_privs.h28 *29 * NOTES30 *	  The Catalog.pm module reads this file and derives schema31 *	  information.32 *33 *-------------------------------------------------------------------------34 */35#ifndef PG_INIT_PRIVS_H36#define PG_INIT_PRIVS_H37 38#include "catalog/genbki.h"39#include "catalog/pg_init_privs_d.h"40 41/* ----------------42 *		pg_init_privs definition.  cpp turns this into43 *		typedef struct FormData_pg_init_privs44 * ----------------45 */46CATALOG(pg_init_privs,3394,InitPrivsRelationId)47{48	Oid			objoid;			/* OID of object itself */49	Oid			classoid BKI_LOOKUP(pg_class);	/* OID of table containing50												 * object */51	int32		objsubid;		/* column number, or 0 if not used */52	char		privtype;		/* from initdb or extension? */53 54#ifdef CATALOG_VARLEN			/* variable-length fields start here */55	aclitem		initprivs[1] BKI_FORCE_NOT_NULL;	/* initial privs on object */56#endif57} FormData_pg_init_privs;58 59/* ----------------60 *		Form_pg_init_privs corresponds to a pointer to a tuple with61 *		the format of pg_init_privs relation.62 * ----------------63 */64typedef FormData_pg_init_privs * Form_pg_init_privs;65 66DECLARE_TOAST(pg_init_privs, 4155, 4156);67 68DECLARE_UNIQUE_INDEX_PKEY(pg_init_privs_o_c_o_index, 3395, InitPrivsObjIndexId, on pg_init_privs using btree(objoid oid_ops, classoid oid_ops, objsubid int4_ops));69 70/*71 * It is important to know if the initial privileges are from initdb or from an72 * extension.
