Q: Why nspacl is null? I'm querying the postgres system table pg_namespace, in particular I'm interested into the field nspacl, which as per documentation https://www.postgresql.org/docs/8.0/catalog-pg-namespace.html is a list of granted privileges to a 'namespace'.
What is not clear from the documentation is the case of null for this field, how is it to be interpreted?

A: Based on some tests, it looks like that null value is for newly created schemas which have not been granted any sort of permissions yet.
