Short Description
bytea data type problem/bug

Long Description
Hi,

It happens when I was trying to test the avalaibility of the new binary data type <bytea> comes with ver 7.2.
As I read from the document, <bytea> will take data from '\\000' (0d)to '\\377' (255d). Although it saves data more than one byte, it looks odd to me that the first digit of the binary data could never be greater than '3'.
Is it the way it should be?
Thanks!

Eric Lu

Sample Code
testdb=> insert into bytetest(id,bdata) values(8,'\\777');
ERROR: Bad input string for type bytea
testdb=> insert into bytetest(id,bdata) values(8,'\\400');
ERROR: Bad input string for type bytea
testdb=> insert into bytetest(id,bdata) values(8,'\\4000');
ERROR: Bad input string for type bytea
testdb=> insert into bytetest(id,bdata) values(8,'\\7000');
ERROR: Bad input string for type bytea
testdb=> insert into bytetest(id,bdata) values(8,'\\3000');
INSERT 488510 1
testdb=> select * from bytetest;
id|bdata

);
