If you're serious about the "important information that we want the user 
to see", then you need to really think about what's important (see 
argument below). Otherwise, the output becomes a text-blurb that nobody 
reads.

Good point, and well covered if a --verbose option is introduced.

What is "important information"? What makes the user really see it?

This is how I perceive the output from initdb:

- The output lists settings for locale, encoding and buffer usage. Why 
are these specific settings be of special interest? Anyone with an 
interest in them knows where to find them anyway. This information is 
not important.
- It lists (the successful creation of ) the internal directory 
structure of the data directory. This information is not important.
- Some output is purely educational and thus belongs in the manual, not 
in a command output ("This user must also own the server process", "You 
can now start the database..."). This information is not important.
- Lot's of info is printed about successful creation of configuration 
files, template databases, conversions, information schema, system 
views, that pg_authid and dependencies has been initialized, database 
copying, etc. This information is not important.

I still think it's much better to have complete silence unless there are 
warnings and/or errors. That makes them much easier to spot. Right now I 
get a "WARNING: enabling "trust" authentication for local connections". 
Now this information *is* important. Unfortunately it's mixed in with 
all the rest unless I use a special redirect of stdout.
