The confusion was my fault because I didn't follow the tutorial,
but the point is valid (others may make similar blunders).

I think that the danger of changing paths in the PGDG binaries is
limited.

It might be a good idea to provide links to the documentation of
other popular binary distributions, e.g. for MacOS.  We can add a
disclaimer that details can differ on these platforms.

I kind of like the "troubleshooting" section, but I am unsure where
to set the limit.  What is there currently doesn't cover all
potential causes (e.g., connection via TCP, see Windows), but
being exhaustive is probably impossible and not even desirable.

On the one hand I can see this section as being helpful for the
host of people who are having problems connecting, on the other hand
the true beginner might have trouble understanding explanations
containing terms like "absolute path" and "Unix-domain sockets".

(Side remark: I think the spelling should be "UNIX domain sockets".)


I'd be sorry if this effort goes to waste, and there are valuable
additions here.

I think that the material in this patch is an improvement over
the "Installation" section in the current tutorial, but that the
other sections ("Architectural Fundamentals", "Creating a Database"
and "Accessing a Database") are better in the original.

And I like the idea of a "troubleshooting" section.

Yours,
