The following documentation comment has been logged on the website:


I'm searching for what a cluster is and how to create one. The
documentation tells me to use initdb -D path/to/cluster. I am told that
this is installed when I installed postgresql. I try to run it with no
success. Searching for an answer I find that I'm supposed to use
pg_createcluster because initdb is version dependent and not made
executable. It seems like there is an omission here as the documentation on
this page also mentions pg_ctl which my system (Ubuntu 18.04) knows nothing
about using the 'which' command. I can imagine that someone might argue
that this is system dependent - I don't know whether that is true or not. I
have generally found the documentation excellent and certainly not inward
looking. For instance the documentation on replication strategies includes
proprietary solutions.

I would suggest that you include a paragraph stating that various operating
systems use other commands to avoid version conflict and suggest the reader
search for '<user-system> pg_ctl'. I can understand why you might not want
to link to external sites in your documentation. (While writing this I have
searched to make sure I'm not writing rubbish and already understand that
pg_createcluster is a Debian solution/variant.)

Thanks for all you do
