How to Log SELECT Statements Having Errors

["Lane Van Ingen" <lvaningen(at)esncc(dot)com>]

We are putting a new application on PostgreSQL 8.0.1 (Windows 2003);
we are coming off of MySQL, and are having a hard time finding all of
the offending SQL calls.

It would help a great deal if I could log the content of any SQL calls
that fail. Am only interested in SELECT statements.

Noticed the following:
(1) The PostgreSQL manual says that config parm 'log_statement' does 
    not appear to handle SELECT statements; true?

(2) Noticed that config parm 'log_min_error_statement' might do it, but
    not sure what each of the DEBUG* and other parameters will buy me 
vs ERROR. I want any statement issued by a client that cannot be executed 
due to an SQL error of any kind.

Can someone advise on this ?
