I agree that it's getting unnecessarily chatty, but things like the
locale that it has detected I think is very useful information to
output. Though I guess the same could be said for a few other things,
but does it *ever' pick anything other than 128Mb/100 for example? :)
The main difference between them is that some information is
informational but unnecessary, but the "next steps instructions" are
*incorrect* in most cases when executed by a wrapper. I'd argue that
even if we show them only with --verbose, we should still have a way
of not outputing the information that's going to be incorrect for the
end user.
I think it boils down to that today the output from initdb is entirely
geared towards people running initdb directly and starting their
server manually, and very few people outside the actual PostgreSQL
developers ever do that. But there are still a lot of people who run
initdb through their wrapper manually (for redhat you have to do that,
for debian you only have to do it if you're creating a secondary
cluster but that still a pretty common operation).
