<p class="MsoNormal"><span lang="EN-US" style="font-size:9.0pt;font-family:"Verdana","sans-serif"">we have now successfully setup a full HA-solution for Postgres incorporating two pg-pool-II instances (heatbeat based fail-over) and a master-slave streaming
replication.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:9.0pt;font-family:"Verdana","sans-serif"">So far, everything works like a charm. However we would now like to enable the load balancing feature of pg-pool if possible.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:9.0pt;font-family:"Verdana","sans-serif"">In general, all of our applications are not using direct SQL or prepared statements but instead are calling user defined functions to do their work.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:9.0pt;font-family:"Verdana","sans-serif"">So basically all calls are Execute some_function(with, some, parameters). In the UDF we have the actual SQL statements then, the updates, inserts and selects…<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:9.0pt;font-family:"Verdana","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:9.0pt;font-family:"Verdana","sans-serif"">Is there a chance that we can do a load balancing of these functions?
