Thanks for the suggestion. I would like to clarify on this a bit. What
do exactly mean by splitting out of the sentence? For example, in one
of the existing messages:

ereport(LOG,
/* translator: %s is SIGKILL or SIGABRT */
(errmsg("issuing %s to recalcitrant children",
send_abort_for_kill ? "SIGABRT" : "SIGKILL")));

Do here words SIGABRT/SIGKILL remain untranslated due to the
translator's comment? I thought this was similar to the message being
proposed but seems like this message construction follows translation
rules better.
