I think this feature would be useful for PgTerminator
(https://github.com/trustly/pgterminator)
a tool which automatically kills unprotected processes that could
potentially be the reason why

When I'm guilty of locking this in the production DB and get killed by
PgTerminator,
it would be nice to know the reason, e.g. that it was PgTerminator
that killed me
and what process I was blocking.
