The first thing to note about the psqlODBC driver (or any ODBC
driver) is that there must exist a driver manager on the system
where the ODBC driver is to be used. There exists a free ODBC
driver for Unix called iODBC which can be obtained via
http://www.iodbc.org. Instructions for installing iODBC are
contained in the iODBC distribution. Having said that, any
driver manager that you can find for your platform should
support the psqlODBC driver, or any other ODBC driver for that
matter. To install psqlODBC you simply need to supply the
--enable-odbc option to the configure script when you are
building the entire PostgreSQL distribution. The library and
header files will then automatically be built and installed with
the rest of the programs. If you forget that option or want to
build the ODBC driver later you can change into the directory
src/interfaces/odbc and do make and make install there. The
installation-wide configuration file odbcinst.ini will be
installed into the directory /usr/local/pgsql/etc/, or
