I found that if you create an index before doing a bulk COPY, yes, it does
take forever to load, and the select is slow.  What I did was drop the
indices built from the COPY and rebuild them.  Speeded the selects up
significantly.  So now I don't build any indices until after I load my
huge databases in.
