Hi tom, Thanks for the answer. Can you tell me about the files concerned by this fix of yours ? I intend to make a patch for the 7.0.2 sources, because, 1) I won't use a CVS version on my production server [ and 2) I'm using the rpm-built postgresql and I didn't manage to easily turn the CVS version into a RPM one ;-) ] Thanks in advance On lun, 25 sep 2000, Tom Lane wrote: > Yeah, there are a lot of geometric operators that neglect to check for > null inputs :-(.
