Tom Lane de1d042f59 Support index-only scans in contrib/cube and contrib/seg GiST indexes. ... To do this, we only have to remove the compress and decompress support functions, which have never done anything more than detoasting. In the wake of commit d3a4f89d8, this results in automatically enabling index-only scans, since the core code will now know that the stored representation is the same as the original data (up to detoasting). The only exciting part of this is that ALTER OPERATOR FAMILY lacks a way to drop a support function that was declared as being part of an opclass rather than being loose in the family. For the moment, we'll hack our way to a solution with a manual update of the pg_depend entry type, which is what distinguishes the two cases. Perhaps someday it'll be worth providing a cleaner way to do that, but for now it seems like a very niche problem. Note that the underlying C functions remain, to support use of the shared libraries with older versions of the modules' SQL declarations. Someday we may be able to remove them, but not soon.
