In a production environment you don't want a user to change your table
statistics.
They could just set default_statistics_target to something stupid,
run ANALYZE and wreck the statistics for everyone.
And then come back to the DBA and complain that things don't work.
We have a policy that users are not table owners, and with the
current behaviour we can be certain that any bad table statistics
are the fault of the DBA or wrong configuration.
