You have to do 2 things in order to allow your container to access your host's postgresql database

1. Make your postgresql listen to an external ip address
2. Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf
