- * @brief Greenplum Partner Connector main header
- *
- * This header contains prototypes for libgppc -- the Greenplum Database Partner
- * Connector.
- *
- * The most common use of the GPPC is to write user defined functions which do
- * not need to be recompiled from one Greenplum Database release to the next.
- *
- * Those user defined functions usually have the following form:
- *
- * \code
- *   GPPC_FUNCTION_INFO(funcname);
- *   
- *   GppcDatum
- *   funcname(GPPC_FUNCTION_ARGS)
- *   {
- *     GppcXXX arg1 = GPPC_GETARG_XXXX(0);
- *     ....
- *     GPPC_RETURN_XXX(result);
- *   }
- * \endcode
- *

-Description: The Greenplum Partner Connector (libgppc) provides a convenient abstraction of the Greenplum Database (GPDB) backend API which will remain constant from one version to the next. For the most part it is targeted at partners and power users trying to write stable user defined functions against GPDB.

-# This directory is for simple regression test for one GPDB release, plus
-# one-compile multi-backend test.  Set USE_PGXS=1 to build against
-# installed GPDB with pg_config, otherwise it's built with source tree.
-#
-# Since we keep the source identical between different GPDB releases,
-# this Makefile finds GP_VERSION_NUM and runs appropriate test cases only.
-# We assume user libraries use PGXS, so this Makefile is a bit too verbose
-# as a simple developer example.  Essentially, user libraries can follow
-# normal PGXS convention except PG_CPPFLAGS and SHLIB_LINK should be set
-# pointing to gppc headers and library.  Or, they can even use only pg_config
-# without PGXS.
