      Allow forcing nullness of columns during bootstrap. · eb68379c
      Andres Freund authored
      Bootstrap determines whether a column is null based on simple builtin
      rules. Those work surprisingly well, but nonetheless a few existing
      columns aren't set correctly. Additionally there is at least one patch
      sent to hackers where forcing the nullness of a column would be helpful.
      
      The boostrap format has gained FORCE [NOT] NULL for this, which will be
      emitted by genbki.pl when BKI_FORCE_(NOT_)?NULL is specified for a
      column in a catalog header.
      
      This patch doesn't change the marking of any existing columns.
