There is no automatic failover solution provided with core postgresql.
(maybe EDB provides in windows but ...)
there are third party OSS solutions,
dhamaniasad/awesome-postgres: A curated list of awesome PostgreSQL
software, libraries, tools and resources, inspired by awesome-mysql
(github.com)
<https://github.com/dhamaniasad/awesome-postgres#high-availability>
These are a few solutions for HA.
There are detailed docs for each and/or blogs, you will have to read them
to figure out which one suits you best.
