<p class=MsoNormal>I don't understand what you mean by "both of time must
not be different". Perhaps you meant that they should be the same
version; the Windows host is running "PostgeSQL 8.2.4 on i686-pc-mingw32,
compiled by GCC gcc.exe (GCC) 3.4.2 (mingw-special)", the Linux host is
running "PostgeSQL 8.2.4 on i686-redhat-linux-gnu, compiled by GCC gcc
(GCC) 4.1.1 (Red Hat 4.1.1-51)". This seems like as close to the
same version as is feasible for Windows/Linux, so I hope it's close enough. <o:p></o:p></p>

The version of PostgreSQL doesn't matter terribly much (one of the design goals
of slony was to provide a smooth upgrade path between PostgreSQL major
revisions). However the version of slony must match exactly between all nodes
in your cluster. <o:p></o:p></p>
