Slony-I and PostgreSQL 8.1
#
          <p>There is a known incompatibility of versions earlier
          than 1.1.5 with version 8.1; you can expect to see the
          following error message when compiling:</p>
          <pre>
slony1_funcs.c:1081: error: too many arguments to function
`Async_Unlisten' 
</pre>

          <p>A patch for both version 1.1 "STABLE" and CVS HEAD has
          been committed to CVS; look at both CVS HEAD as well as
          <tt>REL_1_1_STABLE</tt>. It is in the 1.1.5 release
          candidate described above.</p>

Upgrading Slony-I
#
          <p>Beginning with version 1.0.5 the slon replication
          engine refuses to work against any database that does not
          have the stored procedures for the same version loaded or
          where the shared object containing the C language support
          functions and the log trigger does not match the version
          number.</p>

          <p>This means that the Slony installation on all nodes in
          a cluster must be upgraded at once.</p>

          <p>The proper upgrade procedure is this:</p>

          <ol>
            <li>Stop the slon replication engine on all nodes.</li>

            <li>Install the new Slony version on all nodes.</li>

            <li>Execute a slonik script containing the command
              <pre>

    update functions (id = );
</pre>for every node in the cluster.
            </li>

            <li>Start all slon replication engines.</li>
          </ol>

          <p>For more details, see also <a href=

Libpq requirements
#
          <p>The multithreaded replication engine requires the
          libpq client library to be compiled with
          --enable-thread-safety on certain operating systems.
          Known are thus far Solaris and AIX. Other operating
          systems are known to not require this (Linux-X86,
          FreeBSD-X86, FreeBSD-Alpha, OpenBSD-Sparc64 and OSX). The
          configuration script is broken with respect to the
          --enable-thread-safety switch for Solaris. Please apply
          this patch, configure and recompile libpq: <a href=
          "http://developer.postgresql.org/%7Ewieck/slony1/download/threadsafe-libpq-742.diff.gz">
