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 automatically instead of going through each view and refreshing them one by one? I know that Oracle can do that rather easily but I did not find anything after combing through PostgreSQL documentation.
Looks like current version of PostgreSQL (9.3.1) does not have such functionality, have had to write my own function instead:
CREATE OR REPLACE FUNCTION RefreshAllMaterializedViews(schema_arg TEXT DEFAULT 'public')
RETURNS INT AS $$
DECLARE
r RECORD;
BEGIN
RAISE NOTICE 'Refreshing materialized view in schema %', schema_arg;
FOR r IN SELECT matviewname FROM pg_matviews WHERE schemaname = schema_arg
LOOP
RAISE NOTICE 'Refreshing %.%', schema_arg, r.matviewname;
EXECUTE 'REFRESH MATERIALIZED VIEW ' || schema_arg || '.' || r.matviewname;
END LOOP;
RETURN 1;
END
$$ LANGUAGE plpgsql;
