Log message:
    Clean up BeginCommand and related routines.  BeginCommand and EndCommand
    are now both invoked once per received SQL command (raw parsetree) from
    pg_exec_query_string.  BeginCommand is actually just an empty routine
    at the moment --- all its former operations have been pushed into tuple
    receiver setup routines in printtup.c.  This makes for a clean distinction
    between BeginCommand/EndCommand (once per command) and the tuple receiver
    setup/teardown routines (once per ExecutorRun call), whereas the old code
    was quite ad hoc.  Along the way, clean up the calling conventions for
    ExecutorRun a little bit.
