The following bug has been logged on the website: Bug reference: 16255 Logged by: Robert Ford Email address: (redacted) PostgreSQL version: 12.1 Operating system: Windows Description: I have an simple CTE expression with group by and a string_aggr() function, and Postgresql seems to materialize it anyhow, even if 'not materialized' is instructed. I can't see that this is documented behaviour.
