The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/creating-cluster.html Description:
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 Gary
