Datafusion's SQL dialect has some slight quirks that pertain to Datafusion-specific functionality. For instance, the ability to create an external table.

With regards to ParadeDB, we rely on the Datafusion SQL parser, which can transform the Postgres SQL dialect into a Datafusion logical plan that can be executed by Datafusion. We actually have an open PR that adds support for user-defined functions...it will likely get merged within a few days.

thx for your reply, so postgres is taking care of the parquet files in the background in some way i guess, would it be possible to combine this with something like neon?

We haven't tested. Neon has a pretty unique storage architecture, so I suspect it wouldn't work out-of-the-box, but could with some modifications on our end. We're open to this type of partnership eventually.

If you decide to try it, I believe they now have a way to load in arbitrary Postgres extensions!
