SQLite Schema Migration Bug

This is a repository to reproduce a bug with Ent and the modernc.org/sqlite (non-CGO) SQLite 3 driver.

Reproduce

Simply run go test ./.... The test will run Schema.Create() twice from the generated Ent client. In the real world this is reproducible by starting the application again when using a SQLite file-based DB that already exists. For this bug report I am simply running it twice in the test.

The test shows how this works fine with github.com/mattn/go-sqlite3, but the CGO requirement is a non-starter for my usecase and using the CGO-free driver is the only real option.

Expected Results

I expect that the second pass returns no errors, exactly like mattn/go-sqlite3 does.
