slight mistake in documentation

Hello,

i shortly like to give You a hint about a little mistake in

PostgreSQL 7.1 Documentation
Chapter 3. Data Types
3.8. Bit String Types

Bit strings are strings of 1's and 0's. They can be used to store or
visualize bit masks. There are two SQL bit types: BIT(x) and BIT
VARYING(x); the x specifies the maximum
length. BIT type data is automatically padded with 0's on the right to
the maximum length, BIT VARYING is of variable length. BIT without
length is equivalent to BIT(1), BIT
VARYING means unlimited length. Input data that is longer than the
allowed length will be truncated. Refer to Section 1.1.2.2 for
information about the syntax of bit string
constants. Bit-logical operators and string manipulation functions are
available; see Chapter 4.

Some examples:

CREATE TABLE test (a BIT(3), b BIT VARYING(5));
INSERT INTO test VALUES (B'101', B'00');        ### try: ..VALUES
(B'101', 'B00') instead of: ..VALUES (B'101', B'00')
SELECT SUBSTRING(b FROM 1 FOR 2) FROM test;



Thats it for the moment and
Thanks For That Great Database

Ralf

Why?

I am confused what change you are suggesting here.
