Dbplyr joins fail with default suffixes

To reproduce, join two tables that have column names in common but aren't the join key. Default suffixes (".x" and ".y") are attempted, but obviously column names in Impala (most SQLs I suspect) can't contain dots, so errors are thrown.
Default suffixes should be changed to something valid like "_x" and "_y" when we know we're joining Impala-backed tables.
