Subject: Reduce default value of max_prepared_transactions from 50 to 5.  This
 saves nearly 700kB in the default shared memory segment size, which seems
 worthwhile, and it is a feature that many users won't use anyway.  Per
 Heikki's argument, there is no point in a compromise value --- those who are
 using 2PC at all will probably want it at least equal to max_connections. But
 we can't set it to zero by default without breaking the prepared_xacts
 regression test.
