It would be a good idea to actually find out where it crashes, that
would help you work out what the actual problem is. Just looking at the
code you posted, I only see this other bit that looks a bit suspect:
Datum timest;
bool isnull;
t = PG_GETARG_HEAPTUPLEHEADER(0);
timest = DatumGetTimestamp(GetAttributeByName(t, "ts_today", &isnull));
You're calling DatumGetTimestamp() which would return a timestamp
(probably some structure) but you're storing it in a Datum. Just take
the result of GetAttributeByName directly.
Get at least a backtrace next time it crashes...
Have a nice day,
