I have an idea for this TODO item:
* Allow administrators to safely terminate individual sessions either
via an SQL function or SIGTERM
Lock table corruption following SIGTERM of an individual backend
has been reported in 8.0. A possible cause was fixed in 8.1, but
it is unknown whether other problems exist. This item mostly
requires additional testing rather than of writing any new code.

When we get the termination signal, why can't we just set a global
boolean, do a query cancel, and in the setjmp() code block check the
global and exit --- at that stage we know we have released all locks and
can exit cleanly.
