Probably we don't have to keep the relhasindex info in the
db any longer and we had better keep some info about REINDEX
in memory local to the backend. In fact in the current
implementation the relhasindex is local to the backend
and any backend couldn't see the column committed to
the status off.

Possibly. I couldn't find the appropriate place(way) then
and so #ifdef's are still there.
