Convert Firebird to PostgreSQL.

DBConvert for Firebird to PostgreSQL automates your data's conversion between Firebird, Interbase, and PostgreSQL in any direction.

DBSync for Firebird to PostgreSQL provides database synchronization between Firebird, Interbase, and PostgreSQL. This way, you don't have to re-create the entire target database every time from scratch, but only synchronize changes since the initial copy or since the last start.

Associated file extensions and database names.

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

Why use DBConvert tools?

The DBConvert tools mentioned here are useful for exporting an entire dataset from Firebird to PostgreSQL. Or share some of your tables from the source database with the target database.

It is not a problem to set up either an on-premises PostgreSQL server or a cloud PostgreSQL database.

DBConvert and DBSync for Firebird and PostgreSQL perform database conversion and synchronization tasks between the following databases in any direction:

  1. Firebird
  2. Interbase
  3. PostgreSQL
  4. AWS RDS/ Aurora,
  5. CockroachDB,
  6. Google Cloud SQL for PostgreSQL,
  7. Azure Database for PostgreSQL,
  8. Heroku Postgres

The type mapping feature matches Firebird data types with their closest Postgres equivalents. Or, if you like, you can manually map data types for specific fields.

Database synchronization between Firebird and PostgreSQL.

After copying your data from source Firebird to the target PostgreSQL server, you will need to sync your data. DBSync software keeps your databases totally in sync with Update, Insert and Drop synchronization types.

A trigger-based synchronization algorithm tracks changes in both the source and target databases. The trigger synchronization method increases the re-sync speed by several times.

Bi-directional synchronization helps to update data in both source and destination databases simultaneously.

Using Firebird to PostgreSQL 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 Firebird source database.

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

Connect to Firebird source database from DBConvert

2. Connect to PostgreSQL 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 PostgreSQL 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:

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

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 PostgreSQL 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 Firebird to PostgreSQL.

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 Firebird database to the closest equivalent of the target PostgreSQL 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 Firebird to PostgreSQL

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.

Execution step of DBConvert products

Read more about execution stage available options.

Command line mode

Previously saved sessions can be passed as parameters to Command-Line DBConvert Client. A session keeps Firebird source and PostgreSQL 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:


  • 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
