DESCRIBESQuestion

CAUSED_BYRootCause

PostgreSQL's `ctid` can act like a ROWID, but it is based on the physical tuple location and changes when rows are updated/moved, so it cannot reliably identify the same logical row over time or across statements.

Query Optimization

FIXED_BYSolution

Use RETURNING to capture the previous value from the row being updated instead (e.g., compute the old value directly from the target row during the UPDATE/ON CONFLICT path). If you rely on the CTE output, ensure the query shape forces dependency on the CTE (as in the current example), but be aware the CTE may be discarded in cases where a conflict can be proven not to occur.

FIXED_BYSolution

Use PostgreSQL’s array comparison operator instead, e.g. `SELECT * FROM messages WHERE id = ANY(?::bigint[])` (or pass an array literal like `= ANY('{1,2}'::bigint[])`).
