Pull request overview

Release prep for v1.0.18, focused on fixing grant/ACL diff correctness (esp. owner-change + foreign tables), improving dump efficiency, and strengthening regression coverage/CI.

Changes:

• Fix grant diffing around ALTER ... OWNER TO by introducing asymmetric from_owners / to_owners filtering, and improve ACL parsing for quoted role names.
• Fix foreign table privilege handling (privilege set + GRANT ... ON TABLE emission) and add targeted regression tests.
• Add CI round-trip/idempotency integration tests across multiple PostgreSQL versions; bump crate version + update changelog/test schemas.
