# title:        Provide ability to return all columns using RETURNING (eg RETURNING *)
# decription:   
#                   Ability to use 'returning *' is verified both in DSL and PSQL.
#                   Checked on: 4.0.0.1455: OK, 1.337s.
#               
#                   30.10.2019. NB: new datatype in FB 4.0 was introduces: numeric(38,0).
#                   It can lead to additional ident of values when we show them in form "SET LIST ON",
#                   so we have to ignore all internal spaces - see added 'substitution' section below.
