This is a MySQL feature, where an index is not considered by the planner.
Implementing it should be fairly straightforward, adding a new boolean to
pg_index, and options to CREATE INDEX and ALTER INDEX. I guess VISIBLE would
become a new unreserved keyword.
So, do we want this feature? If we do I'll go ahead and prepare a patch.
I know that it's definitely a feature that I want.
Well, that's encouraging ;-)
Haven't thought
about the syntax, though.
I envisioned:
CREATE INDEX .... [NOT VISIBLE] ...;
ALTER INDEX ... [SET [NOT] VISIBLE] ...;
Let the bikeshedding begin :-)
