Hi,

> But what to do if the input data to circle_in has not the correct form

You can use function elog(type, format, var, ...). In order to do it  
#include "utils/log.h" in your C source. type can have a value (from 
log.h):

#define NOTICE  0       /* random info - no special action */
#define WARN    -1      /* Warning error - return to known state */
#define FATAL   1       /* Fatal error - abort process */

So WARN will stop inserting data to the DB and FATAL will also abort
postgres backend. Arguments "format, var, ..." are similar to printf
arguments.

I think it is the right and only way :-).

Regards and good luck,
