Fix ancient typo in user-defined-aggregates documentation.

The description of the initcond value for the built-in avg(float8)
aggregate has been wrong since it was written.  Noted by Disc Magnet.

The preceding paragraph says that it typically uses a two-element
array for the state value. Maybe this should say two or three-element
given the example that immediately follows it.

Oh, I shouldn't have done that with blinders on :-(. I think probably
we have to explain that float8_accum supports more things than just
average. Will fix as soon as I get back from my doctors appointment.
