How can I troubleshoot PostgreSQL connection issues?
First, check if the PostgreSQL service is running. You can do this by running systemctl status postgresql
.
What if the service is running but I still can't connect?
In that case, verify your connection parameters: host, port, username, and password. Also, check the pg_hba.conf
file for access permissions.
How do I check the pg_hba.conf
file?
You can find it in the data directory of your PostgreSQL installation. Open it with a text editor to review the settings.
What should I look for in the pg_hba.conf
file?
Look for lines that specify the connection method and ensure your user and IP address are allowed to connect.
