It is if you are using a 7.4 or later client to talk to a 7.3 or older
server. The client will first attempt to connect with 7.4 protocol, and
only fall back to the older protocol when that fails. This leaves a
harmless gripe behind in the server's log...

... and evidently that's exactly what the script is doing. I'm not sure
why it's intermixing the server's log output with its own commentary

Can't speak to this one. It could be a file-permissions kind of failure?

Depends how the script invoked initdb --- there's a command line option
telling it which to do.

This seems to be related to Debian's local changes to Postgres; you'll
have to read their documentation to figure out what's up. Or at least
look at their version of the initdb script (in the stock 7.4 script,
line 648 is noticeably further down than you evidently got).

Look at contrib/addepend/README (not sure where Debian puts this, but
it's there in the source tree).
