JOIN pg_class as source_table ON pg_depend.refobjid = source_table.oid Running a query against a server Via the GUI tool pgAdmin. JOIN pg_namespace dependent_ns ON dependent_ns.oid = dependent_view.relnamespaceĭependent_ns.nspname as dependent_schema,ĭependent_view.relname as dependent_view, JOIN pg_class as dependent_view ON pg_rewrite.ev_class = dependent_view.oid JOIN pg_rewrite ON pg_depend.objid = pg_rewrite.oid Get a list of views that have dependencies on other views Here's a query that will bring up your materialized views as well and show you the views' dependencies. LEFT JOIN pg_catalog.pg_stat_all_tables s ON (c.oid = s.relid) LEFT JOIN pg_catalog.pg_attribute a ON (c.oid = a.attrelid AND a.attnum > 0 AND NOT a.attisdropped) THEN pg_catalog.pg_get_viewdef(c.oid, true) Pg_catalog.obj_description(c.oid, 'pg_class') AS comments, If you want more detail you can modify the following to suit your needs: SELECT n.nspname AS table_schema, LEFT JOIN pg_catalog.pg_namespace n ON (n.oid = c.relnamespace) We can use the following command to switch on the expanded display to solve this issue.Pg_catalog.pg_get_userbyid(c.relowner) AS table_owner, The information_schema is a table that holds information about the current database, and we can query it using a select statement to find the public entities in our database.
