Tree view
For pg_isready attempts to make a connection with the sever. If a connection is not successful and we didn't receive any error response from the server, it is a fair assumption to make that server is not running. In this case, it makes perfect sense to not honour the timeout value and return immediately. 

So, this is actually not a bug but rather an expected behaviour.

this is my setup

$ docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -p
3333:5432 --rm -d postgres:11-alpine
4765f8dc49374044d551b3cdb0ce5284905ee1c01bf6a81b2cddf30ab6798bc8

$ time docker run --rm  postgres:11-alpine pg_isready -t 120 -h
10.110.12.163 -p 3333
10.110.12.163:3333 - accepting connections

real    0m0.781s
user    0m0.000s
sys     0m0.031s

$ docker stop some-postgres
some-postgres

$ time docker run --rm  postgres:11-alpine pg_isready -t 120 -h
10.110.12.163 -p 3333
10.110.12.163:3333 - no response
