True enough, but where I've worked on significant projects, there will be 
a hierarchy of system versions:

- developer: replicated as needed, little more data than is required
  for unit testing and module regression tests.

- integration: used for end-to-end tests, performance testing, etc.
  Has enough data to allow meaningful performance measurement and
  realistic database tuning.

- acceptance test: used to check that versions that pass
  integration testing can be installed successfully and that 
  upgrades work without destroying data, etc as well as for
  user acceptance testing. May also be used for end user training.

- the production system.
