# title:        Alter domain operation for domain with collation specified revert its collation to database default
# decription:   
#                   NB: current behaviour contradicts ticket notes!
#                   FB *must* change collation of altered domain, see issue by dimitr in the ticket 06/Jun/20 08:04 AM:
#                   "character set is not a part of the domain itself, it's a part of its data type".
#
