It's not standard, per se, but many ODBC drivers and many databases
(Oracle, MS SQL Server, MySQL, Postgresql, Access, ...) support such a
type. In fact, the structured query language standards SQL92 and SQL99
define the type BIT and BIT VARYING to hold arbitrary bit strings, which
I think is some sort of endorsement for this type.
