David,

Thank you, but we can wait for the version release on Nov 13.  
We are fine running Postgres 17 until then.  No rush.

Many thanks for your quick response and fix.
You can remove me from this thread, if you like.

Lori

The commit is in [1] if you're desperate for it sooner and don't mind patching/building yourself. The next batch of minor version releases is due out on the 13th of November [2].
