It's just in the "annoyance" category: to clear the condition you need
to stop and restart the postmaster. No dump/reload or anything like
that, you just want it to reset shared memory.
The most likely cause of this problem is a backend exiting from an
open transaction without doing AbortTransaction processing. 7.0.*
has a bug that a client disconnect without closing a transaction block
will result in that happening. I posted a patch for it on the patches
list a few weeks ago, or you could pull the current REL7_0_PATCHES
branch (7.0.3-to-be) from the CVS server.
