Okay, thanks. I have worked on that today and applied the patch down
to 14, but without the change to enforce the parameter in the
databases created by pg_regress. Perhaps we should do that in the
long-term, but it is also possible to pass down the option to
PGOPTIONS via command line as compute_query_id is a SUSET or just set
it in postgresql.conf, and being able to do so is enough to address
all the cases I have seen and/or could think about.
