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, Rémi-C
