want to use pgAdmin to connect with AWS RDS (PostgreSQL). Let’s do this step by step.

1. Install pgAdmin on Ubuntu

Run these commands in terminal:

# Update system
sudo apt update && sudo apt upgrade -y

# Install curl, wget, gnupg (if missing)
sudo apt install curl wget ca-certificates gnupg -y

# Add pgAdmin repo key
curl https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/pgadmin.gpg

# Add repo to sources list
sudo sh -c 'echo "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list'

# Update repos
sudo apt update

# Install desktop + web version (recommended)
sudo apt install pgadmin4 -y

2. Run pgAdmin

  • For desktop mode: 
pgadmin4

(It opens pgAdmin GUI)

  • For web mode (browser): 
sudo /usr/pgadmin4/bin/setup-web.sh
  • It will ask you for pgAdmin email + password (used only for login).
  • After setup, pgAdmin web will run at: 👉 http://127.0.0.1/pgadmin4

3. Connect AWS RDS to pgAdmin

  1. Open pgAdmin (desktop or web).
  2. Right-click Servers → Create → Server.
  3. Enter details:
    • Name: AWS RDS
    • Host name/address: your RDS endpoint
    • (e.g. mydb.c9akciq3lqxy.us-east-1.rds.amazonaws.com)
    • Port: 5432
    • Username: (the master username you set, e.g. admin)
    • Password: (your master password)
    • Save.

4. Fix Security Group in AWS

If connection fails:

  1. – Go to AWS Console → RDS → Databases → your DB → Connectivity & security.
  2. – Check VPC security groups.
  3. – Edit inbound rules:
  • Add rule: PostgreSQL (5432) → My IP (your Ubuntu machine’s public IP).(Find IP with curl ifconfig.me).

5. Test Connection from Ubuntu (Optional)

Before pgAdmin, you can check with psql:

sudo apt install postgresql-client -y

psql -h your-rds-endpoint -U admin -d postgres

It will ask for password → then connect.

✅ Now your Ubuntu + pgAdmin is ready, and you can see AWS RDS database, run queries, manage tables, etc.
