I don't think Postgres will even let you install the second node in the same
directory.

Also, you should name the directories /postgres/data Postgres expects to be
installed in a directory named "data".

In fact, if you install Postgres from postgresql.org packages, it'll install
it in "X.Y/data", where X is the major version number, and Y is the minor
version number.
