pgModeler - PostgreSQL Database Modeler - is an open source data modeling tool designed for PostgreSQL. No more DDL commands written by hand let pgModeler do the job for you! This software reunites the concepts of entity-relationship diagrams and the features that PostgreSQL implements as extensions of SQL standards.

Please, let me know how the pgModeler is working on your system! Help to improve this project, give your feedback about the software or report any bug at Issues page. Additionaly, follow the pgModeler profile on Facebook or Twitter and be up-to-date with new features, fixes and releases.

Donate to pgModeler

Much effort, coffee, chocolate, time and knowledge has been devoted to this project so that a usable and constantly improved product could be delivered to the community. If you liked pgModeler and think it deserves a contribution please donate any amount (via PayPal) at project's official site.

Developers and Reviewers wanted!

pgModeler grown bigger and reached a state that its lonely developer cannot handle all the modifications and new features requests. So if you know C++ and Qt framework programming and wants to contribute with coding let me know! I'll be grateful for any help to the project!


For details about installation process from source code visit the Installation section. If you don't want to compile pgModeler there are binaries available for purchase at official site.

Known Issues

  • The diff process still presents false-positive results due its limitations. Sometimes, there is the need to run the process twice to get the full changes.
  • pgModeler does not fully supports the quoted identifier notation. When using quoted identifiers only the following characters are accepted in the middle of names: a-z A-Z 0-9 _ . @ $ - / \ space.
  • pgModeler is unusable in sandboxed Mac OS X installations. To workaround this issue you'll need to deactivate sandbox usage to run pgModeler properly. There is no planning to adapt this tool for sandbox feature in Mac OS X.
  • pgModeler can't be compiled in Microsoft Visual Studio due to use of some gcc/clang extensions.
  • Compiling the source using '-Wconversion' (disabled by Qt in its default) generates a lot of warnings. These warnings are harmless in 99% of times but we can't just ignore them but I don't plan to fix them in a near future (mail me for more details).
  • pgModeler sometimes can crash during the export, import or validation process due to some threaded operations that, depending on size and arrange of the model, causes race conditions.
  • Due to particularities on executing bundles on MacOSX the file association does not work correctly on this system. So it's not possible to open a model file by clicking it on Finder.
