Is PQreset() proper ?

HI all,

I've encountered a database freeze and found it's due
to the reset of connection after abort.

The following is a part of postmaster log.
A new backend(pid=395) started immedaitely after
a backend(pid=394) abort. OTOH postmaster tries
to kill all backends to cleanup shared memory.
However the process 394 ignored SIGUSR1 signal
and is waiting for some lock which would never be
released.

FATAL 2: elog: error during error recovery, giving up!
