Repair CI by setting POSTGRES_PASSWORD env variable

[vasayxtx]

Seems like CI is broken now, it fails when I try to run this locally:

$ circleci local execute --job build --config .circleci/config.yml

...
Error: Database is uninitialized and superuser password is not specified.  
       You must specify POSTGRES_PASSWORD for the superuser. Use                                                                                                                                                
       "-e POSTGRES_PASSWORD=password" to set it in "docker run".                                                                                                                                               
                                                                                                                                     
       You may also use POSTGRES_HOST_AUTH_METHOD=trust to allow all connections

Maintainer of postgres:11-alpine docker image decided to make it more secure by default, so now either the POSTGRES_PASSWORD should be set, or POSTGRES_HOST_AUTH_METHOD should have trust value.
