Hi,
I'm currently adding the support for materialized views to my SQL tool, and noticed that
when creating a materialized view, a rewrite rule is also created that looks just like a
rewrite rule for a "normal" view.
Using pg_get_ruledef() I see that the rule is defined like this:
REATE RULE "_RETURN" AS
ON SELECT TO matview_test DO INSTEAD
SELECT <here comes the select of the mview>
As the materialized view should be a "table" that can be selected from, I
wonder what the purpose of the rewrite rule is?
Regards
Thomas
