pub async fn open_database(
url: &str,
migrations: &Migrator,
) -> Result<PgPool, Error>Expand description
A connection pool to the service’s Postgres database at url, after
creating the database if there’s none yet and bringing it up to date
with migrations. Those two go through direct_database_url, as
they need a session of their own (sqlx serialises migrations with an
advisory lock, so instances may start at once).
