SQL Server to PostgreSQL

SQL Server to PostgreSQL converter is a program to migrate databases from SQL Server and Azure SQL to PostgreSQL on-premises or cloud DBMS. The program has high performance due to low-level algorithms of reading and writing data: more than 10 MB per second on an average modern system. Command line support allows to automate the migration process.

Features Tables, data, indexes, constraints, sequences and views are migrated Spatial data is migrated All versions of PostgreSQL (starting from v9.0) and SQL Server are supported SSL connection for PostgreSQL is supported  Verified support for Heroku and Azure ODBC or any other middleware is not required Fast conversion engine (2MB+/sec on a modern hardware platform) Existing PostgreSQL database can be overwritten, merged or synchronized with SQL Server data Option to filter data using SELECT-queries Option to customize field mapping (modify name, type, default values for every column) Option to export into PostgreSQL script file Quick Launch Stores conversion settings into profile Support for Unicode The product can be customized according to customer requirements

Video Demonstration

Limitations

• Does not convert stored procedures/functions and triggers (MSSQL-to-PostgreSQL Code Converter is able to partially automate this job or our specialists can convert these objects manually as Database Migration Service)
• Demo version converts only 50 records per table
• Demo version does not convert foreign keys and views

Requirements

• Supported OS: Windows 7/8/10/11, Server 2008/2012/2016/2019/2022, Linux with WINE
• Microsoft SQL environment (server or client components of SQL Server must be installed on the same machine where you run SQL Server to PostgreSQL database converter)
• Necessary privileges to write into the destination database

Quick Launch

Once you stored conversion settings into profile you can run the program in Quick Launch mode. Just launch Windows Explorer and double-click on the profile description (.m2p) file with left mouse button. This will cause SQL Server to PostgreSQL database converter to load the necessary settings from the specified profile. Then you will be taken right to the screen with progress indication without entering all conversion settings.

Synchronization

SQL Server to PostgreSQL database converter implements synchronization as combination of insert Microsoft SQL records that are missing in PostgreSQL table and update existing PostgreSQL records with SQL Server data. Source and destination tables must have identical structures and have primary key or unique index defined.

If you need more options to configure the synchronization or want to reduce duration of the process via "incremental" technique, take a look at MSSQL-PostgreSQL Sync, special product to synchronize SQL Server and PostgreSQL databases.

Customize table structure

This feature can be accessed by double click on the corresponding table name in "Selected tables" list of "Step 4 of 5" wizard page.

This will cause the following dialog box to appear: 

To customize type mapping select the appropriate item in the listview on the left and specify new name, type and default value for the field using "Field info" group of controls. Please note that listview on the left contains column attributes of the original types mapping, new custom types and attributes will be displayed in "Field info" controls when the corresponding item is highlighted in the listview.

Views

SQL Server to PostgreSQL converter handles about 90% of syntax constructions involved into SQL Server "CREATE VIEW" statements. Some of the conversion rules are described into this whitepaper.

PostgreSQL script file

SQL Server to PostgreSQL database converter allows to migrate SQL Server database into PostgreSQL format even when there is no connection to PostgreSQL server available for some reason. Following this way, the program converts SQL Server data into a local PostgreSQL script file instead of migrating it to PostgreSQL server directly. The resulting file contains PostgreSQL statements to create all tables and to fill them with the data. Learn how to import dump file into PostgreSQL database.
