Update (2025-12-29 03:04 CET): Recent discussions highlight ongoing difficulties with PostgreSQL connectivity, especially when utilizing SSH tunneling. Useful troubleshooting insights can be gleaned from community posts on platforms like Reddit.

Troubleshooting database connectivity issues can be frustrating. This guide provides practical steps for resolving PostgreSQL connection problems from a Windows machine, specifically when using DBeaver.

Understanding SSH Tunneling and DBeaver

SSH tunneling allows secure access to your PostgreSQL database over untrusted networks. DBeaver is a versatile database management tool with built-in SSH support, essential for remote database connections.

Common Connection Issues

  • Incorrect SSH configuration.
  • Firewall restrictions.
  • Misconfigured PostgreSQL config files.
  • Network latency issues.

Step-by-Step Troubleshooting Guide

To diagnose EOFException errors and other connection issues:

  • Verify SSH settings: Ensure that SSH tunneling is properly configured in DBeaver. The command to establish a tunnel is:
ssh -L 5433:remote_host:5432 user@server
  • Check contact via command line with:
psql -h localhost -p 5433 -U username -W

Reconfiguring postgresql.conf and pg_hba.conf

Ensure your PostgreSQL configuration is sound:

  • Verify listen_addresses in postgresql.conf.
  • Adjust settings in pg_hba.conf to allow connections from trusted IPs.
  • Check configuration location using:
SHOW config_file;

Testing and Verification

After reconfiguring, restart PostgreSQL and test connections again to ensure changes take effect. Verify connectivity both through DBeaver and command line tools.

Conclusion

Addressing PostgreSQL connection issues involves methodical checking of network and configuration settings. With the outlined steps, most common problems can be resolved efficiently.
