# decription:
#                   Added separate code for 4.0: one need to be sure that all changes have been flushed on disk before we launch gstat.
#                   See letter from hvlad, 02.02.2019 22:30.
#                   ::: NOTE :::
#                   !! It looks strange but if we put preparing statement in 'init_script' section than result of 'gstat -i' will be WRONG,
#                   even if we do db_conn.close() before runProgram('gstat' ...) !!
#                   Checked on:
#                       4.0.0.1421: OK, 3.340s. // SS, SC, CS
