How to refresh all materialized views in Postgresql 9.3 at once?

Question

I am loading a bunch of data into a PostgresQL 9.3 database and then I want to refresh all materialized views that depend on the updated tables. Is there a way to do it automat

Answer 1

same method, added the option to run it on all schema's, optionally concurrently.

CREATE OR REPLACE FUNCTION RefreshAllMaterializedViews(_schema TEXT DEFAULT '*', _concurrently BOOLEAN DEFAULT false)
RETURNS INT AS $$
  DECLARE
    r RECORD;
  BEGIN
    RAISE NOTICE 'Refreshing materialized view(s) in % %', CASE WHEN _schema = '*' THEN ' all schemas' ELSE 'schema "'|| _schema || '"' END, CASE WHEN _concurrently THEN 'concurrently' ELSE '' END;
    IF pg_is_in_recovery() THEN 
      RETURN 0;
    ELSE    
      FOR r IN SELECT schemaname, matviewname FROM pg_matviews WHERE schemaname = _schema OR _schema = '*' 
      LOOP
        RAISE NOTICE 'Refreshing %.%', r.schemaname, r.matviewname;
        EXECUTE 'REFRESH MATERIALIZED VIEW ' || CASE WHEN _concurrently THEN 'CONCURRENTLY ' ELSE '' END || '"' || r.schemaname || '"."' || r.matviewname || '"'; 
      END LOOP;
    END IF;
    RETURN 1;
  END 
$$ LANGUAGE plpgsql;
