I'm not aware of a way to terminate a transaction in another session
short of killing its backend process. PostgreSQL 8.0 has a
pg_cancel_backend() function, but it cancels only a backend's current
query, not any outer transaction it might be part of.
Have you discovered what's holding the conflicting lock? It would
be prudent to understand what's happening before killing one
transaction just so another can succeed.
