Once upon a time when I taught myself sql I learned the explicit join
syntax-- I have never really used the where clause to create joins.
With this style of sql I have been building/maintaining a
postgresql-centric web application since postgresql 7.0 and now I am
learning that by writing my sql in this fashion I am constricting the
planner. After reading this:

I am wondering if things are going to change in 7.4? Or should I switch
to placing joins in the where clause when I can? I don't want to have
to worry about my join order-- I would prefer to let the planner do its
thing 95% of the time.
