Database Instance Parameters Configuration

Once a database instance has been created (Database Initialization), the next step is to configure its parameters, modifying the settings in the postgresql.conf file located in the Database directory.

The parameters available for editing are aligned with the installed and selected PostgreSQL version.

Every modification adds a comment line in the postgresql.conf file with the date and user who performed the change.

Final Notes
note

  • Depending on the modified parameter, a RELOAD or even a RESTART of the instance may be necessary. PgSmart will inform which action is required to apply the parameter change.

  • If the Reload or Restart is not confirmed, the configuration will remain in the file until the necessary action is completed.
