Christoph Haller (ch(at)rodos(dot)fzk(dot)de) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
PQescapeBytea parameter #3 size_t *to_length

Long Description
Hi, 

I am referring to 

PostgreSQL 7.2.1 Documentation
Chapter 1. libpq - C Library
1.3. Command Execution Functions
1.3.3. Escaping binary strings for inclusion in SQL queries

I found the line 
"The result string length does not include the terminating zero byte of the result."
is not right. 
The result string length does indeed include the terminating zero byte. 

When I do 

    binarystr = (char *)
            PQescapeBytea((unsigned char *)"\01\02",2,(size_t *)&binarylen);
    printf(" binarylen = %d \n", binarylen) ;

I'll get 
 binarylen = 3 

I also dropped a DocNote, but unfortunately there is no way to 
scroll on longer notes. Maybe you like to fix this, too. 

Regards, Christoph
