Does your PR solve an issue?

No issue filed. Same change as #4502, one version later.

rusqlite 0.42.0 requires libsqlite3-sys ^0.40, so it can't be in the same dependency graph as sqlx (<0.40.0 on main):

error: failed to select a version for `libsqlite3-sys`.
    ... required by package `sqlx-sqlite v0.9.0`
versions that meet the requirements `>=0.30.1, <0.40.0` are: 0.39.1, ...

package `libsqlite3-sys` links to the native library `sqlite3`, but it conflicts with a previous package which links to `sqlite3` as well:
package `libsqlite3-sys v0.40.0`
    ... which satisfies dependency `libsqlite3-sys = "^0.40.0"` of package `rusqlite v0.42.0`

To reproduce: a crate depending on sqlx (any features) and rusqlite = "0.42", then cargo generate-lockfile. With this branch it resolves and builds.

Is this a breaking change?

No. 0.40.0 only differs from 0.39.1 in the bundled SQLCipher version (4.20.0). The SQLite test suite passes locally against 0.40.0, bundled and unbundled, and 0.30.1 still builds.

It would be great if this could make it into 0.9.1 (#4517).
