You almost make sense, but the real problem here is that the date is
converted to date + clock 0 when casted to datetime.  A more
reasonable way to do it would be converting it to date + clock 12:00.
Then one would avoid the whole problem.

It is inserted and read on the same system.  It is crasy that
converting to text and back gives different result:

  pere=> select fname from user_appl where birthdate != birthdate::text::date;
  fname
  -----
  Antal
  (1 row)
 
  pere=>

GNU libc seems to have zoneinfo for Norway back to before 1916, so I
don't think your guess is correct.
