[brainrake]

Adds tests/pg_upgrade/qemu.sh. It boots a build-qemu-image VM, seeds it with the repo migrations and fixtures, then runs initiate.sh and complete.sh and the pgTAP checks in tests/pg_upgrade/tests.

Usage:

IMAGE=<qemu image> PG_UPGRADE_STORE_PATH=<pg17 store path> tests/pg_upgrade/qemu.sh

• Target is hardcoded to PG 17.
• The PG 17 closure is copied into the VM with nix copy.
• initiate.sh reads PG_UPGRADE_STORE_PATH instead of fetching the catalog from S3.
• Single VM. The two-VM shared data disk flow is not covered.

Testing

• 17 to 17
• 15 to 17
