Install problems (libpq.so.1)

Hello:

where can I find libpq.so.1?

I am trying to install DBI/DBD for postgreSQL. I found
perl-DBI-1.06-1.i386.rpm on rpmfind.net and it installed just fine but
when I tried to install perl-DBD-Pg-0.91-1.i386.rpm I get a message that

this package needs libpq.so.1. What package do I need to install to
find libpq.so.1? Is there a later version of perl-DBD in RPMS format
out there?
I am really adverse to putting anything on my system that is not in rpm
format.

libpq is the C programmer's interface to PostgreSQL server, and is
included with PostgreSQL. Do a "locate libpq" and see what version you
have. You might be able to get away with creating a symbolic link to one
of the libpq's you have. If not, you'll need to find an older version of
PostgreSQL or libpq or find a newer version of perl-DBD-Pg-0.91. Sometimes
you have to skirt the RPM.

saying it cannot find libpq.so.1.

Even though I copied libpq.so to libpq.so.1 locate libpq does not list
libpq.so.1. If I can make locate find the .so.1 then I think the rpm instal

will work. I do not need to use the C programmers interface only perl will
be
connecting to postgres so I hope I will not run into compatibility problems
by
installing a version of DBD that was not made for PostgreSQL 6.4.2.

I really cannot go back and install a previous version of PostgreSQL because
I
am working on a large open source project and all other members of the team
are on 6.4.2.

The shared library's identity is compiled into it and I don't think you can
do what you want by renaming it. It is probably undesirable in any case
because the new library has changed its interface - that's why it changed
its identity.

What you need to do is get the source of DBD and compile it so that it will link to libpq.so.2. This is a lot more likely to succeed than hacking your
libraries around.
