About This Tool
The Online Postgres Tester is a streamlined service to test PostgreSQL database connectivity. Using the native PHP PDO Postgres driver, it attempts a secure connection to your remote server, verifying the host, port, credentials, and database name.
It's a fast way to confirm a database is reachable and your credentials are correct, without launching pgAdmin or the psql command-line tool — ideal for debugging firewall rules or checking a newly created role's access.
How to Use This Tool
Enter connection details
Fill in the host, port, username, password, and database name for your PostgreSQL server.
Click "Test Connection"
The tool attempts a live connection over the native PHP PDO Postgres driver.
View the result
See an instant success or failure response, including connection latency.
Common Use Cases
Firewall Testing: Check if pg_hba.conf and server firewalls allow remote connections.
Configuration Check: Ensure newly created Postgres roles have correct access to the intended databases.
Cloud Compatibility: Test AWS RDS for PostgreSQL, Supabase, Neon, or Heroku Postgres databases.
Developer Workflow: Quickly validate connection parameters before embedding them into a backend application.
Why Use This Tool
Instant Verification
Quickly confirm database accessibility without launching pgAdmin or the psql CLI.
Reliable Diagnostics
Returns exact PostgreSQL error codes natively (e.g., role does not exist, database missing).
Secure Design
Connections are made ephemerally and credentials are never stored.
Speed Measurement
Tracks the actual latency for the complete TCP connection and authentication handshake.
