+# - Find the PostgreSQL installation.
+# In Windows, we make the assumption that, if the PostgreSQL files are installed, the default directory
+# will be C:\Program Files\PostgreSQL.
+#
+# This module defines
+#  PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
+#  PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
+#  PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)

+# ----------------------------------------------------------------------------
+# History:
+# This module is derived from the module originally found in the VTK source tree.
+#
+# ----------------------------------------------------------------------------
+# Note:
+# PostgreSQL_ADDITIONAL_VERSIONS is a variable that can be used to set the
+# version mumber of the implementation of PostgreSQL.
+# In Windows the default installation of PostgreSQL uses that as part of the path.
+# E.g C:\Program Files\PostgreSQL\8.4.
+# Currently, the following version numbers are known to this module:
+# "9.1" "9.0" "8.4" "8.3" "8.2" "8.1" "8.0"
+#
+# To use this variable just do something like this:
+# set(PostgreSQL_ADDITIONAL_VERSIONS "9.2" "8.4.4")
+# before calling FIND_PACKAGE(PostgreSQL) in your CMakeLists.txt file.
+# This will mean that the versions you set here will be found first in the order
+# specified before the default ones are searched.
+#
+# ----------------------------------------------------------------------------
+# You may need to manually set:
+#  PostgreSQL_INCLUDE_DIR  - the path to where the PostgreSQL include files are.
+#  PostgreSQL_LIBRARY_DIR  - The path to where the PostgreSQL library files are.
+# If FindPostgreSQL.cmake cannot find the include files or the library files.
+#
+# ----------------------------------------------------------------------------
+# The following variables are set if PostgreSQL is found:
+#  PostgreSQL_FOUND         - Set to true when PostgreSQL is found.
+#  PostgreSQL_INCLUDE_DIRS  - Include directories for PostgreSQL
+#  PostgreSQL_LIBRARY_DIRS  - Link directories for PostgreSQL libraries
+#  PostgreSQL_LIBRARIES     - The PostgreSQL libraries.
+#
+# ----------------------------------------------------------------------------
+# If you have installed PostgreSQL in a non-standard location.
+# (Please note that in the following comments, it is assumed that <Your Path>
+# points to the root directory of the include directory of PostgreSQL.)
+# Then you have three options.
+# 1) After CMake runs, set PostgreSQL_INCLUDE_DIR to <Your Path>/include and
+#    PostgreSQL_LIBRARY_DIR to wherever the library pq (or libpq in windows) is
+# 2) Use CMAKE_INCLUDE_PATH to set a path to <Your Path>/PostgreSQL<-version>. This will allow find_path()
+#    to locate PostgreSQL_INCLUDE_DIR by utilizing the PATH_SUFFIXES option. e.g. In your CMakeLists.txt file
+#    SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "<Your Path>/include")
+# 3) Set an environment variable called ${PostgreSQL_ROOT} that points to the root of where you have
+#    installed PostgreSQL, e.g. <Your Path>.
+#
