Ok.

Sorry, it was not a typo, but the information was not very explicit.
I have looked at 3 libraries: libevent, libuv and libev.
libuv is quite lively, last updated 2023-06-30.
libev is an often cited library, which indeed seems quite dead, so I was
"noting" that I had discarded it, but it looked like a typo.

The wait event postgres backend implementation would require a lot of work
to be usable in a client context.
My current investigation is that libuv could be the reasonable target, if
any, especially as it seems to provide a portable thread pool as well.
