It is not sent to the server as a trailing comment. The following file 
is sent to the server like this.

File:
/**/;
/**/

Commands:
PQexec(..., "/**/;");
PQexec(..., "/**/");

If this has to be fixed it should be in the client. I think people would 
complain if we broke the API by starting to throw an exception on PQexec 
with a string containing no actual query.
