       The PQparamSendQuery() and PQparamSendQueryPrepared()  functions  execute  an  asynchronous  paramertized
       query  using  the  parameters  in  a  PGparam.   The  only  difference  between  these  functions is that
       PQparamSendQuery() expects a parameterized command  string  while  PQparamSendQueryPrepared()  expects  a
       stmtName previously prepared via PQprepare().

       Both  functions  take  a  param  argument, which must contain the same number of parameters as either the
       command string or previously prepared stmtName.  Internally,  the  param  is  transformed  into  parallel
       arrays that are supplied to a PQsendQueryParams() or PQsendQueryPrepared() call.

       The  resultFormat  argument  indicates  if  text  or  binary  results are desired; a value of zero or one
       respectively.  PQgetf supports both text and binary result formats, with  the  exclusion  of  arrays  and
       composites which only support binary.

       After  successfully  calling PQparamSendQuery() or PQparamSendQueryPrepared(), call libpq´s PQgetResult()
       one or more times to obtain the results.

UsingPQparamSendQuery
       The example uses PQparamSendQuery() to execute a query using a PGparam.

              PGparam*param=PQparamCreate(conn);if(!PQputf(param,"%text%int4","ACTIVE",CAT_CAR)){fprintf(stderr,"PQputf:%s\n",PQgeterror());}else{intsuccess=PQparamSendQuery(conn,param,"SELECT*FROMtWHEREstatus=$1ANDcategory=$2",1);if(!success)fprintf(stderr,"PQparamSendQuery:%s\n",PQgeterror());elseget_and_print_results(conn);/*callsPQgetResult()*/}PQparamClear(param);UsingPQparamSendQueryPreparedPQparamSendQueryPrepared()      is      behaves     identically     to     PQparamSendQuery(),     except
       PQparamSendQueryPrepared() requires that a statement has been previously prepared via PQprepare().  Also,
       a stmtName is supplied rather than a parameterized command string.

       parameters in a PGparam.

       On success, a non-zero value is returned.  On error, zero is returned and PQgeterror(3) will  contain  an
       error message.
