Yeah, I like Cristoph's suggestion fine.  It meets my criteria of
"includes timestamp and PID" and overall seems reasonable.   If we
adopted that across the board, it wouldn't be too much different from
what Peter proposed for the regression test.  Just to compare.

    log_line_prefix = '%t [%p-%l] %q%u@%d '
    log_line_prefix = '%t [%p]: [%l] %qapp=%a '

So Peter's got %p and %l separated by "]: [" whereas Christoph has
them separated only by a dash.  Presumably that's minor.  Then they've
both got %q.  After that, Christoph has %u@%d, which seems reasonable
for an actual system, and Peter's got app=%a, which is better for the
regression tests because the user name will depend on the UNIX
username of the person running the tests.

So how about we adopt both suggestions, except changing Peter's to '%t
[%p-%l] %qapp=%a ' so that they are a bit more similar?  I bet that
would make more people happier than it would make less happy.
