(7.1) BIT datatype

Some SQL92 functionality is missing from the BIT and VARBIT types.

It should be possible to enter hexadecimal values as:
 B'[<bit>...]'[{<separator>...'[<bit...]'}...] X'[<hexdigit>...]'[{<separator>...'[<hexdigit...]'}...]

(Cannan and Otten: SQL - The Standard Handbook, p.38)

but the hexadeximal form is not accepted.

For example:

bray=# \d junk           Table "junk"Attribute |     Type     | Modifier 
-----------+--------------+----------id        | character(4) | not nullflag1     | bit(1)       | flags     | bit(8)
   | 
 
Index: junk_pkey

bray=# insert into junk values ('BBBB',B'0',X'FF');
ERROR:  Attribute 'flags' is of type 'bit' but expression is of type 'int4'You will need to rewrite or cast the
expression
