I'm running 7.4Beta1 with pg_autovacuum.  In one of my operations which
is executed frequently, a REINDEX is done after a COPY.  Well, VACUUM's
are being executed by pg_autovacuum, and my app is loosing the deadlock.

Is there a way I can prevent this from happening?  I can obviously
acquire a LOCK before doing the REINDEX (which one?), but it looks like
this should be happening anyway by both the VACUUM and REINDEX
statements.

Help?
Rob
