Ask HN: Why are postgresql-common commands all over the place?

Is it just me or I honestly feel the command-line interface for the postgresql-common package seems to be poorly designed. pg_createcluster, pg_ctl, pg_dump, pg_reload, pg_wrapper, pg_lscluster, pg_createcluser, pg_ctlcluster. The list goes on. initdb, createdb doesn't seem to be pg specific. Is there a single wrapper to manage pretty much all services? Apologies for the rant but I feel like I had to put this out somewhere.
