I did turn autoprewarm on, windows server 2019 and postgresql 11.2 it
runs fine even with huge_pages=on (Thanks to neha sharma). As Thomas
said error is coming from per database worker and main worker waits
till per data database worker exists so from code review I do see an
issue of having an invalid handle in per database worker. A
reproducible testcase will really help. I shall see to recheck the
code again but I am not much hopeful without a proper testcase.
