Reporting the bind-parameter on an error

Hi,

Currently, the SQL statement that causes an error condition is reported
in the server log. On the other hand, the bind-parameter is not reported
as following.

FATAL: terminating connection due to administrator command
STATEMENT: UPDATE tbl SET name = $1 WHERE id = $2
LOG: shutting down

The bind-parameter is useful information for debugging. So, I made
the small patch which reports the bind-parameter together with
the SQL statement on an error.

FATAL: terminating connection due to administrator command
STATEMENT: UPDATE tbl SET name = $1 WHERE id = $2
DETAIL: parameters: $1 = 'hoge', $2 = '1'
LOG: shutting down

Any comments welcome!
