libpq.so.4

Hello,

I have the same issue as this poster with libpq.so.4:
http://www.nabble.com/8.3.0-upgrade-td16093803.html

In short, I've upgraded to 8.3.1 from 8.1 on RHEL 4 (with some CentOS
packages). I have apps with dependencies of libpq.so.4 but this is no
longer available. 8.3.1 provides libpq.so.5 and the compat-libs
provide libpq.so.3.

At the moment maintaining package management integrity is not a must -
getting back to 100% package-controlled files can wait until the
machine is replaced. Upgrading the dependent software is not an option.
With that in mind, any suggestions on options?

What I've thought of trying so far is
1) creating a symlink called libpq.so.4 towards libpq.so.5 - slightly
dangerous due to possible API changes?
2) extracting a copy of libpq.so.4 from the previous RPM release of
postgres and manually uploading it
3) building a custom compat package - I don't know how to do this
though.

but I'm unaware of the pros and cons of these.

Any comments appreciated.

Regards
Oliver
