<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana","sans-serif"" lang="EN-US">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.</span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana","sans-serif"" lang="EN-US">So far, everything works like a charm. However we would now like to enable the load balancing feature of pg-pool if possible.</span></p>

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana","sans-serif"" lang="EN-US">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.</span></p>
<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana","sans-serif"" lang="EN-US">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…</span></p>

<p class="MsoNormal"><span style="font-size:9.0pt;font-family:"Verdana","sans-serif"" lang="EN-US">Is there a chance that we can do a load balancing of these functions?
