If it supports the same for index-scans I *really* like it and even proposed a
patch earlier (4A16A8AF.2080508@anarazel.de)
I still find myself constantly wishing to have something like that...
Especially when wondering if it might be worthwile to add another column
(which is implemented as an additional qual atm) should get included in a
multiicolumn index.
It was shot down at the time because it might break some explain-parsers
expectations. Imho that argument is less valid these days.
