- PgFoundry and External Projects
+ External ProjectsPostgreSQL is a complex software project,
and managing the project is difficult. We have found that many
enhancements to PostgreSQL can be more
- efficiently developed separately from the core project.
-
-
-
- To help our community with the development of their external projects,
- we have created the PgFoundry.
- PgFoundry is built using the
- GForge software project and is similar to SourceForge in its feature set. If
- you have a PostgreSQL related Open Source project that you would like to
- develop and need project management resources such as mailing lists, forums,
- bug tracking, and CVS, please feel free to create a new project.

- currently closed to new projects in favor of PgFoundry, it still contains
- many active and relevant projects. There are other popular PostgreSQL
- related projects that are hosted independently as well at other community
- sites such as SourceForge. You should

+
