[GENERAL] OR-clause support for indexes

Hi.

 

Back in 9.6 dev-cycle Teodor (from PostgresPro) posted a patch providing indexed OR-clauses: https://commitfest.postgresql.org/8/454/

Sadly it didn't make it to 9.6, and wasn't re-submitted for the 10 dev-cycle.

 

@Teodor; Do you have plans to submit a patch for PG-11?

And, have you made any progress making it work for btree?
