   * Query-result printing support for frontend code
   *
   * This file used to be part of psql, but now it's separated out to allow
   * other frontend programs to use it.  Because the printing code needs
   * access to the cancel_pressed flag as well as SIGPIPE trapping and
   * pager open/close functions, all that stuff came with it.
