the difference between a run-time type cast and casting a literal string
to a specific type.  Minor editorial work in same area.

Oliver Elphick.  A few other minor cleanups while at it.

And listing QNX 6 as both supported and unsupported is probably not helpful.

pg_regress doesn't see it and you don't get any port-specific
comparisons.

This is so obvious that I would like to make it 'official'.

Seems like the theology around bytea<>text casting kept me from
seeing the simple :)

granted the lock when awakened; the signal now only means that the lock
is potentially available.  The waiting process must retry its attempt
to get the lock when it gets to run.  This allows the lock releasing
process to re-acquire the lock later in its timeslice.  Since LWLocks
are usually held for short periods, it is possible for a process to
acquire and release the same lock many times in a timeslice.  The old
spinlock-based implementation of these locks allowed for that; but the
original coding of LWLock would force a process swap for each acquisition
if there was any contention.  Although this approach reopens the door to
process starvation (a waiter might repeatedly fail to get the lock),
the odds of that being a big problem seem low, and the performance cost
of the previous approach is considerable.

to the client before closing the connection.  Before 7.2 this was done
correctly, but new code would simply close the connection with no report
to the client.
