Hi,
This patch seems like quite a good improvement. One thing I've not
really looked at but am slightly concerned in passing: Are there cases
where we now would do a lot of predicate pruning work even though the
overhead of just evaluating the qual is trivial, e.g. because there's
only one row due to a pkey? The predtest code is many things but
lightning fast is not one of them. Obviously that won't matter for
analytics queries, but I could see it hurt in OLTPish workloads...
Greetings,
Andres Freund
