This passed CI, so I have marked it as Ready for Committer. Further
comments are still welcome, of course, but if there are none, I intend
to get it committed in a few days.

I'm not really happy with our usage of the translatable description
field for things such as %b in log_line_prefix or the ps display; I
think we should use the shorter names there instead. Otherwise, you end
up with log lines that look something like this (visible in a server
with %b in log_line_prefix, which the TAP tests as well as pg_regress
have):

2025-12-08 21:38:04.304 CET autovacuum launcher[2452437] DEBUG: autovacuum launcher started

where the bit before the PID is marked for translation. I think it
should rather be

2025-12-08 21:38:04.304 CET autovacuum[2452437] DEBUG: autovacuum launcher started

where that name (the same we'll use in log_min_messages) is not
translated.

However, this issue is rather independent of the patch in this thread,
so I'm going to discuss it in another thread; the name string though is
added by this patch.
