This isn't that surprising either: a query inside a function is
often translated into a "generic" plan that doesn't depend on
specific parameter values, typically sacrificing runtime to
avoid repeated planning.  Does it get any better if you do
"set plan_cache_mode = force_custom_plan" before running the
function?
