Care has been taken to make it possible to install <productname>PostgreSQL</>

into shared installation locations (such as

<filename>/usr/local/include</filename>) without interfering

with the namespace of the rest of the system. First, the

string <quote><literal>/postgresql</literal></quote> is

string <quote><literal>postgres</></quote> or <quote><literal>pgsql</></quote>. For

example, if you choose <filename>/usr/local</filename> as

prefix, the documentation will be installed in

<filename>/usr/local/doc/postgresql</filename>, but if the

prefix is <filename>/opt/postgres</filename>, then it will be

in <filename>/opt/postgres/doc</filename>. The public C header files of the

client interfaces are installed into

<varname>includedir</varname> and are namespace-clean. The

into private directories under

<varname>includedir</varname>.

See the documentation of each interface for information about how to get at

the its header files.

Finally, a private subdirectory will also be created, if appropriate,

under <varname>libdir</varname> for dynamically loadable modules.
