All we need is an easy explanation of the problem, so here it is.
I’m trying to alter a table definition, but it’s dependent on a materialized view which is managed by RedShift Auto Materialization and not by us. So attempting
ALTER TABLE my_table
ALTER COLUMN my_column TYPE VARCHAR(100);
Errors with
[0A000] ERROR: cannot alter type of a column used by a materialized view
So I attempt to drop the materialized view
DROP MATERIALIZED VIEW pg_automv.auto_mv_53022635;
Which gives a permission error
[42501] ERROR: permission denied for schema pg_automv

Method 1
It’s not possible, they are fully managed by AWS. The solution from AWS support is to turn off AutoMV and reboot to drop all AutoMV.
That is harsh.
Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
