DESCRIPTION:
------------

This is version 1.9.0 of pgsql_perl5 (previously called pg95perl5).

Pgsql_perl5 is an interface between Larry Wall's language perl version 5 and 
the database PostgreSQL (previously Postgres95). This has been done by using 
the Perl5 application programming interface for C extensions which calls the 
Postgres programmer's interface LIBPQ. 



COPYRIGHT:
----------

You may distribute under the terms of either the GNU General Public
License or the Artistic License, as specified in the Perl README file.



IF YOU HAVE PROBLEMS:
---------------------

Please send comments and bug-reports to <pgsql-interfaces@postgresql.org>

Please include the output of perl -v,
                         and perl -V,
           the version of PostgreSQL,
           and the version of pgsql_perl5
in your bug-report.


REQUIREMENTS:
-------------

  - build, test and install Perl5          (at least 5.003)
  - build, test and install PostgreSQL     (at least 6.5)


PLATFORMS:
----------

  This release of pgsql_perl5 has been developed using Linux 2.2 with 
  dynamic loading for the perl extensions. Let me know, if there are 
  any problems with other platforms. 


INSTALLATION:
-------------

The Makefile checks the environment variables POSTGRES_INCLUDE and
POSTGRES_LIB, to find the library libpq.so and the include file
libpq-fe.h. 

If you are using pre-compiled binaries for postgresql and you 
can't find libpq.so and libpq-fe.h most probably you missed to
install an additional development-package for postgresql. 

1.   perl Makefile.PL
2.   make
3.   make test
4.   make install

( 1. to 3. as normal user, not as root ! )


TESTING:
--------

Run 'make test'.
Note, that the user running this script must have been created with the access 
rights to create databases. Do not run this script as root ! 

If testing fails with the message 'login failed', please check if access 
to the database template1 as well as pgperltest is not protected via pg_hba.conf. 

If you are using the shared library libpq.so check if your dynamic loader 
finds libpq.so. With Linux the command /sbin/ldconfig -v should tell you, 
where it finds libpq.so. If ldconfig does not find libpq.so, either add an 
appropriate entry to /etc/ld.so.conf and re-run ldconfig or add the path to 
the environment variable LD_LIBRARY_PATH. 
A typical error message resulting from not finding libpq.so is: 
  Can't load './blib/arch/auto/Pg/Pg.so' for module Pg: File not found at

Some linux distributions have an incomplete perl installation. 
If you have compile errors like "XS_VERSION_BOOTCHECK undeclared", make a 
          'find .../lib/perl5 -name XSUB.h -print'
If this file is not present, you need to recompile and reinstall perl. 

Also RedHat 5.0 seems to have an incomplete perl-installation: if 
you get error message during the installation complaining about a 
missing perllocal.pod, you need to recompile and reinstall perl. 

SGI users: if you get segmentation faults make sure, you use the malloc which 
           comes with perl when compiling perl (the default is not to).

HP users: if you get error messages like:
              can't open shared library: .../lib/libpq.sl
              No such file or directory
          when running the test script, try to replace the
          'shared' option in the LDDFLAGS with 'archive'.

DOCUMENTATION:
--------------

Detailed documentation can be found in Pg.pm. Use 'perldoc Pg' after 
installation to read the documentation.
