System Catalogs
pg_depend
Overview
The pg_depend tracks relationships between database objects, such as tables, columns, constraints, and indexes. It mimics the PostgreSQL system catalog pg_depend.
Please note that Oxla doesn’t support the custom types.
Columns

pg_depend are applicable to every type of relation.The following columns are available for querying in pg_depend:

|---|---|---|
classid | int | This column represents the OID of the system catalog the dependent object is in |
