Note: XCONLY: The following description applies only to Postgres-XC.
This section describes external projects of the Original PostgreSQL. Not all the project products are tested with Postgres-XC. You may find specific remarks for some of them. Otherwise, they're not tested well so far.
Note: The following description applies both to Postgres-XC and PostgreSQL if not described explicitly. You can read PostgreSQL as Postgres-XC except for version number, which is specific to each product.
PostgreSQL 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.
