CREATE INDEX USING GIST(timerange);

On 1.3 million rows this took only 30 seconds.
on 70 million its already taken over a day. I swear it didn't take this long
on version 9.3


Is there some kind of known bug with GIST? CPU is at 4% or less and ram is
at 150mbs
IO usage is at 100% but most of it is writes? (like 3.5mbps!) which looks
good but actually the size of the disk is only increasing by like 8 BYTES
per second.

This is really odd and I don't want to wait an indefinite amount of time.
