Catalogs: pg_depend
48.18. pg_depend
The catalog pg_depend
records the dependency relationships between database objects. This information allows DROP
commands to find which other objects must be dropped by DROP CASCADE
or prevent dropping in the DROP RESTRICT
case.
See also pg_shdepend
, which performs a similar function for dependencies involving objects that are shared across a database cluster.
