Roman Khabibov
roman.habibov at tarantool.org
Thu Apr 11 20:33:26 MSK 2019
According to the ANSI standart, ltrim, rtrim and trim should
be merged into one unified TRIM() function. The specialization of
trimming (left, right or both and trimming charcters) determined
in arguments of this function.
Closes #3879
