To check the dependency of a table in PostgreSQL, you can use the pg_depend catalog view. Here's an example query: n`SELECT n.nspname AS schema, c.relname AS table_name, d.def FROM pg_class c JOIN pg_attribute a ON c.oid = a.attrelid JOIN pg_namespace n ON c.relnamespace = n.oid JOIN pg_depend d ON a.attnum = ANY(d.objid) WHERE c.relkind = 'r' AND d.classid = c.oid AND n.nspname NOT IN ('pg_catalog', 'information_schema');`
