Description:

Would be nice to add the limits to the doc, according to my pg15 instance I
can't set bgwriter_delay more than 10000 ms. (I set it to 60 s and got a
FATAL upon startup)

We do print the valid range for other bgwriter GUCs so it doesn't seem like an
unreasonable idea.  It might not help too many, but not printing it at all
clearly doesn't really help anyone.
