Just a side comment here: VACUUM ANALYZE has nothing whatever to do
with "reordering" indexes.  What it does that a plain VACUUM does
not do is gather statistics about the table contents (minimum, maximum,
and most common value of each column, at present).  These stats are then
used by the optimizer to make better planning choices.  At least we'd
like to think they're better, Lord willin' an' the creek don't rise...
