The subsequent discussion pointed out that you probably shouldn't have
ANALYZEd right at that point, but I didn't see anyone suggest that you
should have done TRUNCATEs rather than delete all/vacuum full. The
TRUNCATE way is a good deal faster, and it will also eliminate index
bloat while vacuum full won't.
BTW, 7.3.2 has several known serious bugs; I'd recommend an update to
7.3.8, if not upgrading to 7.4.*.
