How are you importing/defining the metadata for the postgresql source?
Until [TEIID-5502] Add better JDBC array support - JBoss Issue Tracker the jdbc importer didn't import source array types as their actual type.
Thank you, we are indeed using the default JDBC importer. An update to 11.2 fixed this for us, with a free JSON data type to boot. Great job, thanks!
