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

This is version 0.73 of DBD-Pg.
DBD-Pg is a PostgreSQL interface for Perl 5 using DBI.

For further information about DBI look at:
http://www.fugue.com/dbi/

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 <[email protected]>

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

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

- build, test and install Perl 5 (at least 5.002)
- build, test and install the DBI module (at least 0.91)
- build, test and install PostgreSQL (at least 6.3)

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

This release of DBD-Pg has been developed using Linux 2.0 with
dynamic loading for the perl extensions. Let me know, if there
are any problems with other platforms.

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

The Makefile checks the environment variable POSTGRES_HOME as well
some standard locations, to find the root directory of your Postgres
installation.

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 *AND* users ! 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 in 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:
install_driver(Pg) failed: Can't load './blib/arch/auto/DBD/Pg/Pg.so'
for module DBD::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.

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).
"David R. Noble" <[email protected]>

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'.
Dan Lauterbach <[email protected]>

FreeBSD users: if you get during make test the error message:
'DBD driver has not implemented the AutoCommit attribute'
recompile the DBI module and the DBD-Pg module and disable
optimization. This error message is due to the broken
optimization in gcc-2.7.2.1.

Sun Users: if you get compile errors like:
/usr/include/string.h:57: parse error before `]'
then you need to remove from pgsql/include/libpq-fe.h
the define for strerror, which clashes with the definition
in the standard include file.
