So the RelationGetDescr() cannot get a segv even if the table does not exist. # I modified contrib/passwordcheck that way and saw RelationGetDescr() # doesn't get segv in the shown context. I guess the segv comes from another place, or something else has broken memory until there. but anyway more information is needed for people to diagnose your situation more closely. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
