Theory 1: postgres is packaged in a "postgresql-server" package
and the OP only installed the base (client-side) package.

Theory 2: postgres is installed into some directory not in the OP's
PATH, such as /usr/sbin. Since it's primarily used as a daemon,
this'd be a reasonable thing for a packager to do.

I'd bet a nickel on #1, though, because I've not seen too many
packagers put postgres somewhere other than where they put psql.
"Separate server package" is extremely common though.
