Hey list,
another tricky C function interface problem :
How to write a set returning function, that returns for each row an array?
it seems like the main function SRF_RETURN_NEXT takes Datum and so I can't use PG_RETURN_ARRAYTYPE_P().
Shall I encapsulate the array into a composite field (only 1 field : the double array)
I looked a lot for an example wihtout success.
Help greatly appreciated,
thanks,
Cheers,
