Yes, you right, I just must run LOAD - after LOAD had complete all works good. Thanks.
Btw, how I can convert TEXT field to a CString one? I had tried to use
char *cnum = PG_GETARG_CSTRING(0) instead of
text tnum = PG_GETARG_NAME(0), but it's not worked properly. Is any function
to convert text object to a null-terminated string??? Thanks again.
