Function to refresh all materialized views in a PostgreSQL 9.3 database.
PostgreSQL 9.3 supports materialized views but does not have a functionality to refresh the views except for issuing refresh command for each view individually. After asking on stackoverflow and not finding solution (http://stackoverflow.com/questions/19981600/how-to-refresh-all-materialized-views-in-postgresql-9-3-at-once) I decided to write my own function.
To refresh views in public schema:
select RefreshAllMaterializedViews()
To refresh views in other schema:
select RefreshAllMaterializedViews('my_schema');
