Case https://issues.apache.org/jira/browse/CALCITE-6444 proposes a library for Redshift. This would be welcome, but I see a potential problem.
Redshift and Postgres are so similar that almost every function in Postgres is also in Redshift. I'd rather not have to log bugs every time someone adds a function in Postgres and forgets to add it to Redshift. Would it be better if, when a function is in the Postgres library, it is included in the Redshift library *unless explicitly excluded* (using the 'exceptLibraries' property I propose in the case)?
