 From the "idle thoughts in the middle of the night" department:

I don't know if this has come up before exactly, but is it possible that 
we could get a performance gain from building multiple indexes from a 
single sequential pass over the base table? If so, that would probably 
give us  a potential performance improvement in pg_restore quite apart 
from the projected improvement to be got from running several steps in 
parallel processes. The grammar might look a bit ugly, but I'm sure we 
could finesse that.
