This looks awesome. Does it work with CockroachDB?
Because I was imagining something like Knex when I read "interface for" I'll mention that this is a Graphical User Interface.
CockroachDB claims to have compatibility with Postgres, but I wasn't able to make a cockroach db sample database using the postgresql dump files(cockroachdb doesn't seem to support schemas). I'll have to revisit it again to make the project work with cockroach db.
