How "fixed" is the btree index growth issue in 7.4? Does it mean no more
reindexing ever? Or does it mean reindexing once a month instead of once a
week?

Chris,

reindexing ever? Or does it mean reindexing once a month instead of once a
week?

The Free Space Map has been extended to cover indexes. So this means that
with proper FSM tuning, one may be able to eliminate or tremendously postpone
REINDEX.

Without proper FSM tuning, of course, you're no better off than 7.3.

Try it and tell us ;-). I think it will depend on your usage patterns
to some extent.
