QUESTION
I am using listagg to group users having same permissions, based on the query from the below stack question, tweaked it a bit for my needs. How do I view grants on Redshift
This fails saying listagg is compute node function and should be used on user created table. Any way to use listagg on catalog tables and has_*_privilege function both of which runs on leader node?

Answered 2021-Jun-07 at 11:35No.
As you have correctly understood, listagg
is a function implemented by Redshift, rather than being inherited from Postgres/Paraccel, and it has been implemented only on the worker nodes.
The has
function is from Postgres, and is implemented only on the leader-node.
The query planner will not permit a query using a leader-node only function to recruit worker nodes, so you cannot call listagg
.
(BTW, if I remember correctly, that 'v' for reltype is also going to pick up materialized views.)
As an aside, you can in fact obtain the information you are looking for directly from the system tables, but this is a long and complex undertaking. I am a Redshift specialist and it took me two months for the first version, although I was working at the time.

Install pg_view
You can use pg_view like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
