# title:        AVG - Integer OverFlow
# decription:   
#                   Refactored 14.10.2019: adjusted expected_stdout/stderr
#                   25.06.2020, 4.0.0.2076: changed types in SQLDA from numeric to int128 // after discuss with Alex about CORE-6342.
#                   09.07.2020, 4.0.0.2091:
#                       NO more overflow since INT128 was introduced. AVG() is evaluated successfully.
#                       Removed error message from expected_stderr, added result into expected_stdout.
