Thanks for all those hints! I've now adapted my code as you recommended and it works fine, although I'm not certain what DirectFunctionCall1 and DatumGetCString actually do (it seems that the only documentation of these functions is in the source code, and I'm too lazy to sift through it at the moment). -- Felix E.
