I think it will be really hard to generate such a test in pg_dump,
because default we are compiling --without-lz4, which means we have
only one compression option available, and if there is only one option
available then the column compression method and the default
compression method will be same so the dump will not generate an extra
command of type ALTER TABLE... SET COMPRESSION.
