master one?<br><br>The short simple answer is no.<br><br>For slony to work correctly, all versions of slony on master and slaves must be the same version. But most important, slony _cannot_ handle missing columns. That is specifically stated in the Current Limitations section. <span class="PRODUCTNAME">Slony-I</span> does not automatically
propagate schema changes, nor
does it have any ability to replicate large objects. <br>http://slony.info/documentation/slonyintro.html#INTRODUCTION<br><br>It is your responsibility to insure that all schemas are identical. That is why EXECUTE SCRIPT is used to maintain the changes. <br>http://slony.info/documentation/stmtddlscript.html<br><br>You do have the option of only replicating tables that are identical across all schemas, but I doubt that would be of help to you in this scenario.<br><br><div id="RTEContent"><font size="4"><span style="font-weight: bold; font-family: arial; color: rgb(0, 0, 255);">Melvin Davidson </span></font><br> <font size="3"></font><font size="3"><span style="font-weight: bold; font-family: courier;"></span></font></div><br></td></tr></table><br>
