Tom, while porting our patches for GiST from 7.0.3 to 7.1 we got a problem with equal operator for _int4 - src/backend/access/gist.c:540 /* did union leave decompressed version of oldud unchanged? */ FunctionCall3(&giststate->equalFn, PointerGetDatum(ev0p->pred), PointerGetDatum(datum), PointerGetDatum(&result)); this call produces core when one of the PointerGetDatum(ev0p->pred) or PointerGetDatum(datum) is NULL We use internal postgres function for array comparison -&giststate->equalFn is references to array_eq There is no problem in 7.0.3 Do you have any idea what could be a reason for such behaivour ? (bug or feature :-) regards, Oleg _____________________________________________________________ Oleg Bartunov, sci.researcher, hostmaster of AstroNet, Sternberg Astronomical Institute, Moscow University (Russia) Internet: oleg@sai.msu.su, http://www.sai.msu.su/~megera/ phone: +007(095)939-16-83, +007(095)939-23-83
