basename(lookup) Hint???

[sarah]

Good afternoon. Anyone have a clue what the "basename(lookup)" text in a create projection statement indicates?

For example:

CREATE PROJECTION public.retail_sales_super /*+basename(code_value),createtype(L)*/

It's the basename of the projection. For example, a projection basename can be customer_dimension_vmart and when segmented will have _b0, _b1 appended.
