# title:        FB3: Stored function accepts duplicate input arguments
# decription:   
#                    02.02.2019. Replaced 'show func' with query to RDB$FUNCTIONS table: we have just to ensure that no function did appear in DB.
#                    (removed 'show func' because its output is mutable and can be directed either to STDERR or STDOUT in diff. FB versions).
#                    Checked on:
#                       4.0.0.1421: OK, 1.512s.
