How to Fix PostgreSQL "password authentication failed"

April 2026

PostgreSQL auth failures usually come down to the wrong user, password, or connection target. Here is the clean Skippr checklist.

Short Answer

PostgreSQL password authentication failed means the source credentials do not match what the database expects. In Skippr, that usually means the username, password, host, or database target is wrong.

Confirm the exact Postgres user and password, then rerun skippr connect source postgres with the corrected values.

Why This Error Happens

Source connection failures are usually simpler than they look. Skippr is just making a normal Postgres connection, so the fix is usually in the credentials or target settings.

• Wrong Postgres username or password.
• Pointing at the wrong host or database.
• Using a user that exists but does not have access to the target database.
• Loading credentials from an environment file that does not match the current shell.

How to Fix It with Skippr

If you want a clean isolation step, test the same credentials with a Postgres client first. Once they work there, reconnect the source in Skippr.

• Verify the exact Postgres username and password.
• Confirm the host, port, and database name are correct for the environment.
• Make sure the chosen user has read access to the tables Skippr needs.
• Rerun skippr connect source postgres with the corrected values.
• Run skippr doctor if you want a quick prerequisites check before the full pipeline.

When Skippr Is the Better Path

Once the Postgres source is connected, the rest of the workflow stays compact. You do not have to bootstrap raw loading, staging, and the first warehouse path in separate products.

That saves the team from fixing a source login in one place and rebuilding the rest of the path somewhere else.
