refresh_immv(immv_name, with_data) is a function to refresh IMMV like REFRESH MATERIALIZED VIEW command. It has two argument. immv_name is incrementally maintainable materialized view's name, and with_data is an option that is corresponding to the WITH [NO] DATA option. When with_data is set false, the IMMV gets unpopulated. One of differences between IMMVs unpopulated by this function and normal materialized views unpopulated by REFRESH ... WITH NO DATA is that such IMMVs can be referenced by SELECT but return no rows, while unpopulated materialized views are not scanable. The behaviour may be changed in future to raise an error when unpopulated an IMMV is scanned.
