    the following to regress/sql/tests.

    If applying by hand note that the setup_... must run before
    the run_... (that I splitted these two was due to the errors
    that occured when creating rules and using them then in the
    same session - I'll post another fix for this later).

    BTW: the regression tests sanity_checks and alter_table fail
    now due to the remove of some indices and the oidint4 and
    oidname types. At least expectes should be set to the current
    results.

    Thanks.
