My rule of thumb with the datetime code is that if it looks bogus,
it probably is :-(

There are a lot of fixed-size local buffers in that code.  The ones
used in output routines seem defensible since the string to be generated
is predictable.  The ones that are used for processing input are likely
wrong.  OTOH I'm not eager to throw a palloc into each of those code
paths ... can we avoid that?
