That is very surprising, thanks. Will fix. I've been experimenting with reusing psql sessions and backends for queries in TAP tests, since some Windows animals seem to take a significant fraction of a second *per query* due to forking and startup costs. ~100ms or whatever is nothing compared to that ~2000ms silliness, but it still adds up over thousands of queries. I'll post an experimental patch soon, but this discussion has given me the idea that pg_regress might ideally be able to reuse processes too, at least sometimes...
