porting from 7.2 -> 7.4

I'm trying to port some replication code from 7.2 -> 7.4 and am running 
into a block.

In the file:
  /src/backend/tcop/postgres.c

My diff was for:

void
pg_exec_query(char *query_string)
{

       pg_exec_query_string(query_string, whereToSendOutput, 
             QueryContext);


}


But the pg_exec_query_string function seems to have left.  Can someone 
share with me insight as to what it has been replaced by?

Thanks,
- Brandon
