So, if I'm not mistaken:
hash indexes -> can't be used in CLUSTER gin indexes -> can't be used in CLUSTER that leaves: btree -> ok expression btree -> I have to find a way to compute the expression for each tuple: hints? gist -> how can I get something "comparable" by tuplesort? Or should I rule it out from the seq scan + sort path?
