I'm working with our performance testing team to rerun our load tests
with the patch applied. However, the current infrastructure doesn't
support deploying custom PG builds, so it's unlikely we'll be able to
provide results in time for the upcoming minor releases.
Also, is it significant effort to produce a patch for PG 17? Running the
load tests against master would make it chancy to compare the results
with the data we already have.
