This allowed ordinary users to acquire superuser status, for example. The escalation-of-privilege risk exists only in 8.1.0-8.1.2. However, in all releases back to 7.3 there is a related bug in <TT CLASS="COMMAND" >SET SESSION AUTHORIZATION</TT > that allows unprivileged users to crash the server, if it has been compiled with Asserts enabled (which is not the default). Thanks to Akio Ishida for reporting this problem.</P ></LI ><LI ><P >Fix bug with row visibility logic in self-inserted rows (Tom)</P ><P >Under rare circumstances a row inserted by the current command could be seen as already valid, when it should not be.
