PostgreSQL to Firebird conversion and synchronization.

DBConvert for Firebird and PostgreSQL is designed to convert data between PostgreSQL, Firebird, and Interbase in any direction.

DBSync for Firebird and PostgreSQL synchronizes data between PostgreSQL, Firebird, Interbase database nodes to keep the data identical after the initial transfer or since the last start.

Associated file extensions and database names.

  1. PostgreSQL is also known as Postgres, PgSQL, PG.
  2. Firebird / Interbase (related files: fdb, ib, gdb).
  3. Interbase is known as Borland Interbase, Embarcadero Interbase.

Six reasons for using DBConvert/ DBSync tools.

  1. In fact, you get a multitool that can convert and synchronize data in any combination, including local and managed databases in the clouds listed here:
  2. DBConvert tool minimizes the problems you may encounter when migrating from PostgreSQL to Firebird/ Interbase. Your database schemas, tables, views, and relationships will be migrated accurately and quickly to meet the target database's requirements while maintaining the integrity of the database.
  3. By default, all database tables are selected for migration. Or you can customize the items to convert.
  4. The type mapping feature matches Postgres data types with their closest Firebird equivalents. Or, if you like, you can manually map data types for specific fields.
  5. You can save customized sessions and schedule subsequent jobs to run automatically.
  6. After copying your data from source PostgreSQL to the target Firebird, you will need to sync your data. DBSync software keeps your databases totally in sync with Update, Insert and Drop synchronization types.

Using PostgreSQL to Firebird conversion and synchronization tools.

When launching the DBConvert or DBSync application in GUI mode, it seamlessly guides you through the steps to initiate database migration or synchronization:

1. Connect to PostgreSQL source database.

Specify the username/password and host/port parameters if your source database requires login credentials.

Connect to PostgreSQL source database from DBConvert

2. Connect to Firebird destination database.

Specify parameters for the destination database similar to the source, defining connection settings and username/password pairs.

Connect to Firebird target database from DBConvert

NOTE #1: Each DBConvert or DBSync tool's name comprises two different databases, enabling any specified database to operate as the source or destination. Furthermore, the same type of database can function as both the source and destination.

NOTE #2: Connections to cloud databases (e.g., Amazon RDS, Google Cloud, or Azure SQL) aren't explicitly specified in the user interface but use the same settings as traditional on-premises databases.

NOTE #3: Connections to source and target databases remain active until you close the DBConvert/DBSync application or reopen new connections.

Refer to our documentation for specific source/ destination configurations for different databases.

3. Configure database migration options.

Specify the tables, fields, indices, and views you want to transfer to the Firebird destination database by checking/unchecking the corresponding boxes.

Customize general database/ tables settings. Or configure specific table , field, index object individually when migrating data.

Explore our articles in the user's manual about Configuring database migration options. for detailed information.

The screenshot below summarizes the general features available in DBConvert software.

4. Detection of potential database migration issues. Errors and Warnings

The database enforces certain relations on the data, and on the customization step, an intelligent error checker verifies all possible data integrity and referential integrity issues. It highlights any problems before migration starts.

By default, DBConvert attempts to automatically map the database types of the source PostgreSQL database to the closest equivalent of the target Firebird database types. However, you can manually change the data types for the entire database globally using the "Global mapping" or individually for each field.

Explore the Intelligent error checker for more information. on errors and warnings

5. Execution. The final stage of data migration.

Initiate the conversion or synchronization process after configuring source and destination databases in the previous steps.

Click the "Commit" button to start conversion. Here, you can also monitor the migration/synchronization process.

Optionally save connection settings and configuration parameters into the session file to schedule the launching of sync or migration jobs regularly.

Command line mode

Pass previously saved sessions as parameters to the Command-Line DBConvert Client. A session retains PostgreSQL source and Firebird target database connection settings with other specified options.

NOTE: First, run the software in GUI mode to create a session file with initial parameters.

Built-in scheduler.

Our applications include a built-in scheduler to run database migration and sync jobs at specified times. Set the scheduled date and time to execute job sessions automatically.

Supported OS:


  • Necessary privileges to write into database on the target PostgreSQL server (this requirement is optional as there is an option to overcome the restrictions using dump file or PHP Script)
  • Firebird 2.x.x and higher
