One simple improvement would be to change the documentation's view of
REINDEX -- at the moment, it says that it's only useful for rebuilding
"corrupted indexes". If it's a legitimate maintainence activity for
certain query loads, it should get a more positive spin.

Also, could we enhance REINDEX to not require an exclusive table lock?
Without looking at the code, I would think that we could at least allow
for SELECTs (using seqscans or other indexes) while a REINDEX is running.

Cheers,

Neil
