I think it's a very useful feature (only tested on Linux)

FATAL: terminating connection due to administrator command
DETAIL: signal sent by PID 1592705, UID 1000.

I'm wondering if there is a standard style for displaying such values in
DETAIL. For instance, the checkpoint LOG is formatted like this:

LOG: checkpoint complete: ... write=0.044 s, sync=0.071 s, ...

I'm not sure if it applies for DETAIL, but at least it's what the
example at the error style guide[1] suggests:

Detail: Failed syscall was shmget(key=%d, size=%u, 0%o).

Thanks!

Best, Jim
