Table 51.17. `pg_default_acl` Columns

Column Type Description
`oid` `oid` Row identifier
`defaclrole` `oid` (references `pg_authid`.`oid`) The OID of the role associated with this entry
`defaclnamespace` `oid` (references `pg_namespace`.`oid`) The OID of the namespace associated with this entry, or 0 if none
`defaclobjtype` `char` Type of object this entry is for: `r` = relation (table, view), `S` = sequence, `f` = function, `T` = type, `n` = schema
`defaclacl` `aclitem[]` Access privileges that this type of object should have on creation

A `pg_default_acl` entry shows the initial privileges to be assigned to an object belonging to the indicated user. There are currently two types of entry: “global” entries with `defaclnamespace` = 0, and “per-schema” entries that reference a particular schema. If a global entry is present then it overrides the normal hard-wired default privileges for the object type. A per-schema entry, if present, represents privileges to be added to the global or hard-wired default privileges.

Note that when an ACL entry in another catalog is null, it is taken to represent the hard-wired default privileges for its object, not whatever might be in `pg_default_acl` at the moment. `pg_default_acl` is only consulted during object creation.
