There are some other conditions as well. Postgres needs to be shut down when
you do the copy. The CPU needs to be the same architecture. Postgres should
be built with the same options (some data representations are controlled by
config options). Potentially different compilers (used to build Postgres on
the two systems) could cause problems as well (by changing structure layouts).
