I think the first step is fixing the `SqlToRel` to make earlier `FROM` bindings available to the `LATERAL` input. > > ## Footnotes > 1. https://www.postgresql.org/docs/16/sql-select.html [↩](#user-content-fnref-1-34707c1f2caf3760a3ce090ed62c61c5) Thanks -- I have had that paper on my reading list for a while. I think it is time to bump it to the top -- This is an automated message from the Apache Git Service.
