DESCRIPTION:
  Original test see in:
  https://github.com/FirebirdSQL/fbtcs/blob/master/GTCS/tests/EXT_REL_0_3_D.script

NOTES:
  [31.07.2022] pzotov
  FB config must allow creation of external tables, check parameter 'ExternalFileAccess'.
  Otherwise: SQLSTATE = 28000 / Use of external file at location ... is not allowed ...
  Checked on 3.0.8.33535, 4.0.1.2692, 5.0.0.591
