Conversion and Synchronization

Firebird to PostgreSQL Conversion

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.

Enterprise-Grade Open Source Migration

Transition from Firebird to PostgreSQL's advanced open-source platform with enterprise features, comprehensive cloud support, and world-class performance capabilities.

Supported Database Formats

File extensions and database platform compatibility

Firebird / InterBase

Related file extensions:

.fdb .ib .gdb

Also known as Borland InterBase, Embarcadero InterBase

PostgreSQL

Also known as:

Postgres PgSQL PG

World's most advanced open source relational database

Bi-directional Support

Full conversion and synchronization support in any direction between all supported database formats.

Why Migrate from Firebird to PostgreSQL?

Unlock advanced database capabilities and enterprise features

Advanced SQL Features

Full SQL standard compliance with advanced features like window functions, CTEs, stored procedures, and comprehensive indexing strategies.

Rich Data Types

Support for JSON, arrays, geospatial data, ranges, and custom data types. Perfect for modern applications requiring complex data structures.

Extensible Architecture

Rich extension ecosystem including PostGIS for geospatial data, TimescaleDB for time-series, and hundreds of other specialized extensions.

Cloud-Native Ready

Available on all major cloud platforms with managed services, automatic scaling, backup, and high availability options.

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.

Supported Database Platforms

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

Firebird Firebird
InterBase InterBase
PostgreSQL PostgreSQL
AWS RDS/Aurora AWS RDS/ Aurora
CockroachDB CockroachDB
Google Cloud SQL Google Cloud SQL
Azure Database Azure Database
Heroku Postgres Heroku Postgres

Advanced Migration Features

Comprehensive data type mapping and synchronization capabilities

Intelligent Data Type Mapping

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.

Automatic Type Conversion

Smart automatic mapping between Firebird and PostgreSQL data types with manual override options for specialized field requirements and custom data structures.

Database Synchronization Features

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.

Advanced Sync Methods

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.

PostgreSQL to Firebird

Using Firebird to PostgreSQL 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 Firebird source database

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

Connect to Firebird source database from DBConvert
2

Connect to PostgreSQL destination database

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

Connect to PostgreSQL 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 PostgreSQL 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.

4

Detection of potential database migration issues

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 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.

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 conversion/synchronization process.

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

DBConvert Software Features

Command line mode

Pass previously saved sessions as parameters to the Command-Line DBConvert Client. A session retains 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, 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 conversion and sync jobs at specified times. Set the scheduled date and time to execute job sessions automatically.

Find more Information about the built-in scheduler.

System Requirements

Ensure your system meets these requirements for optimal performance

Supported OS

Requirements

  • 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
