Hi, I've got a couple of questions. I was using numeric_out like this:
DatumGetCString(DirectFunctionCall1(numeric_out, d)); Why do I have to use DirectFunctionCall1 instead of calling numeric_out? I was suggested to use numeric_send instead of numeric_out, however when changing the function names in the above example, the whole expression returns 8. Always 8. I check with: char *x = DatumGetCString(DirectFunctionCall1(numeric_send, d)); PLy_elog(NOTICE, x). And my main question: is there any documentation about those internal functions, which use and when etc? thanks Szymon
