Convert PostgreSQL to Firebird.

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 you start DBConvert or DBSync application in GUI mode it guides you through several steps to set up the database migration or synchronization:

1. Connect to PostgreSQL source database.

If a source database requires you to log in, you can specify a user name/ password and host/ port parameters.

Connect to PostgreSQL source database from DBConvert

2. Connect to Firebird destination database.

Specifying parameters for destination database looks like the same as for source. Usually, it consists of defining connection settings and username/password pairs.

Connect to Firebird target database from DBConvert

NOTE #1: Every DBConvert or DBSync tool has two different databases in its name. That means any specified database from a pair can be set up as a source or destination. Besides, the same type of database may be set up both as a source or destination.

As an example, here is the list of possible migration directions with on-premises databases:

  • PostgreSQL to Firebird
  • Firebird to PostgreSQL
  • PostgreSQL to PostgreSQL
  • Firebird to Firebird

NOTE #2: Don't be confused by the fact that connections to cloud databases like Amazon RDS, Google Cloud, and Heroku are not explicitly specified in the configuration of a source or destination in the DBConvert / DBSync interface. To connect to Cloud database instances, use the same settings as you do for traditional on-premises databases.

NOTE #3: Your connections to source and target databases stay active until you close DBConvert/ DBSync application or reopen new connections on "source" and "destination" steps.

Read more about the specific source/ destination configurations for different databases.

3. Configure database migration options.

At the next step, you can specify precisely which tables, fields, indices, views you want to transfer to the Firebird destination database. Just check/ uncheck the box in front of each database object you want to convert.

Customize general database/ tables settings. Or set up a particular table , field, index individually when migrating data from PostgreSQL to Firebird.

Check out our articles about Configure database migration options. for detailed information.

The screenshot below sums up general features available in DBConvert software solutions.

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

The database typically constrains certain relations on the data that cannot be violated. On the customization step, a smart error checker verifies all possible Data integrity and Referential integrity issues and highlights them, if any, before performing a migration.

By default, DBConvert tries 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.

Check out Smart error checker. Errors and Warnings for more information.

5. Execution. The final stage of data migration from PostgreSQL to Firebird

Once you configure source and destination databases for migration in the previous steps, you can start the actual conversion or synchronization process.

Click the "Commit" button to start conversion. Also, here, you can monitor the migtation/ 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

Previously saved sessions can be passed as parameters to Command-Line DBConvert Client. A session keeps PostgreSQL source and Firebird target database connection settings with other specified options.

Example: C:\Program Files\DBConvert\firebird2postgresqlPro\firebird2postgresqlPro_Cons.exe /Session:"Session_Name"

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

Built-in scheduler.

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

Supported OS:


  • Firebird 2.x.x and higher
  • 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)
