z_pivot_rsc:define_custom_pivot

[heiheshang]

I think you can make a list, not a tuple
now
z_pivot_rsc:define_custom_pivot("phone",[{phone,"varchar(11)"}],Context).
can do
z_pivot_rsc:define_custom_pivot([{"phone",[{phone,"varchar(12)"}]},{"contact",{contact_id,"integer"}]}])

Note: especially for the return value of the custom pivot observer.

It seems to me to do better through postgresql triggers
