2 H.1. Client Interfaces #
4 There are only two client interfaces included in the base PostgreSQL
6 * libpq is included because it is the primary C language interface,
7 and because many other client interfaces are built on top of it.
8 * ECPG is included because it depends on the server-side SQL grammar,
9 and is therefore sensitive to changes in PostgreSQL itself.
11 All other language interfaces are external projects and are distributed
12 separately. A list of language interfaces is maintained on the
13 PostgreSQL wiki. Note that some of these packages are not released
14 under the same license as PostgreSQL. For more information on each
15 language interface, including licensing terms, refer to its website and
