I know you reviewed this, Michael, so you're aware; 2d3389c28 did
recently document that we'd only break this in minor versions as a
last resort. So, I agree that it sounds like a master-only fix is in
order.
For the record, the docs [1] read:
"Generally, it can be assumed that queryid values are stable between
minor version releases of PostgreSQL, providing that instances are
running on the same machine architecture and the catalog metadata
details match. Compatibility will only be broken between minor
versions as a last resort."
