The patch looks good and cleaner.  It looks like the code works as expected.  As before, I ran one INSERT statement
withPgJDBC, with gdb's breakpoints set on enable_timeout() and disable_timeout().  I confirmed that enable_timeout() is
calledjust once at Parse message, and disable_timeout() is called just once at Execute message.
 

I'd like to wait for Tatsuo-san's thorough testing with pgproto.
