Based on Tom's recent comments, I'd be inclined to handle this via
doing a CLUSTER, which has the "triple heroism effect" of:

 a) Reorganizing the entire table to conform with the relevant index order,
 b) Having the effect of VACUUM FULL, and
 c) Having the effect of REINDEX

all in one command.

It has all of the "oops, that blocked me for 20 minutes" effect of
REINDEX and VACUUM FULL, but at least it doesn't have the effect
