H.1. Client Interfaces #

There are only two client interfaces included in the base PostgreSQL™ distribution:

All other language interfaces are external projects and are distributed separately. A list of language interfaces is maintained on the PostgreSQL wiki. Note that some of these packages are not released under the same license as PostgreSQL™. For more information on each language interface, including licensing terms, refer to its website and documentation.
