Postgres supports both:

test=# create table test (a bit(3));
CREATE
test=# insert into test values (B'101');
INSERT 3431020 1
test=# insert into test values (b'101');
INSERT 3431021 1
test=# insert into test values ('B101');
INSERT 3431022 1
test=# insert into test values ('b101');
INSERT 3431023 1
test=# select * from test;
a
-----
101
101
101
101
(4 rows)

In fact, some of our apps actually _rely_ on the old 'b101' syntax...
Although these could be changed with some effort...
