pgAdmin and postgresql on WSL2

readme.md

Show config file location with sudo -u postgres psql -c 'SHOW config_file'

Edit the file, default: sudo nano /etc/postgresql/14/main/postgresql.conf

listen_addresses = '*'
port = <remember-port>

sudo ufw allow <port>

Edit sudo nano /etc/postgresql/14/main/pg_hba.conf

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

sudo service postgresql restart and sudo ufw reload

Connect using pgAdmin as usual with 127.0.0.1 and the port.

This is very insecure, use only for local dev-environments.
