Remember to change the password values

Run the Docker Containers

docker compose up -d

edit the postgress config (optinal)

open the config file

nano postgres_data/postgresql.conf

Change the following values

listen_addresses = '*'
max_connections = 100
shared_buffers = 16GB
work_mem = 256MB
maintenance_work_mem = 2GB
dynamic_shared_memory_type = posix
max_wal_size = 1GB
min_wal_size = 80MB

set these to what makes most sense for you

These values should also be set bet not necessarily changed

log_timezone = 'Etc/UTC'
datestyle = 'iso, mdy'
timezone = 'Etc/UTC'
lc_messages = 'en_US.utf8'
lc_monetary = 'en_US.utf8'
lc_numeric = 'en_US.utf8'
lc_time = 'en_US.utf8'
default_text_search_config = 'pg_catalog.english'
