Sem acesso ao servidor | PostgreSQL: administração e otimização do banco

Bom dia mestre, surgiu uma duvida referente a aula 3 de "tuning de banco" onde vc inicia a aula dentro do servidor postgres, porem como montei um laboratório docker e suvi ima imagem postgres igual está na aula, após eu fazer o comando "pg_clt stop" ele derruba a imagem do postgres na docker, como seria possível acessar o servidor como vc esta acessando na aula se dar restart através da docker?

Conf do arquivo "postgresql.conf"

postgres@ba781188b3d3:~/data$ cat postgresql.conf | grep -v '#' | grep -ve '^$'
listen_addresses = '*'
max_wal_size = 1GB
min_wal_size = 80MB
log_connections = on
log_timezone = 'Etc/UTC'
datestyle = 'iso, mdy'
timezone = 'Etc/UTC'
default_text_search_config = 'pg_catalog.english'
log_destination=stderr

Comandos executados:

root@ba781188b3d3:/# su postgres
postgres@ba781188b3d3:/$ pg_ctl status -D /var/lib/postgresql/data/
pg_ctl: server is running (PID: 1)

Obs: Um detalhe que esqueci de mencionar, estou me conectando com o servidor via browser, não sei se isso faz diferença, seguem mais detalhes detalhes do que tenho rodando na docker
