the problem in ci is similar to #592 (comment). executing make test-compat locally passes

Hey @KKould!

One of the join tests is not passing with SQLite:

limbo % sqlite3 --version
3.45.2 2024-03-12 11:06:23 d8cd6d49b46a395b13955387d05e9e1a2a47e54fb99f3c9b59835bbefad6af77 (64-bit)
limbo % SQLITE_EXEC=sqlite3 ./testing/join.test
Error: in prepare, near ".": syntax error
  rowid from users u left join products as p using(p.rowid) where u.rowid >= 10
                                      error here ---^

    select u.rowid, p.rowid from users u left join products as p using(p.rowid) where u.rowid >= 10 limit 5;
} {1..."
    (file "./testing/join.test" line 117)

Also, could you just rebase this against main, which hopefully fixes the CI failures
