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 null
flag1 | 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
