propose: detail binding error log

Hi, hackers.

I had a error message while using PostgreSQL.

"ERROR:  42804: column "a" is of type boolean but expression is of type
integer at character 25
LOCATION:  transformAssignedExpr, parse_target.c:529"

This error is a java jdbc binding error.
column type is boolean but bind variable is integer.

I want see that value of bind variable at a server log.

java code:
pstmt = connection.prepareStatement("insert into test values (?)");
pstmt.setInt(1, 1);

I could not see that value at a server log, by changing any servier
configurations.

That case is debuged to client only.

So, I propose that error value of bind variable will be displayed at a
server log.
in parse_target.c:529,
input parameter value of that node not containded value of column at
client.

I want more detail error log.
