I had a successful and working PostgreSQL connection when using version 8.1. When I updated to 8.4, it stopped working. I have tried several combinations (such as UNICODE, UTF8 and others) to no avail and am wondering if maybe the AutoIt driver needs to be updated? It creates the connection object just fine and generates the error on the Open... pgdb.au3 : ==> The requested action with this object has failed.: $ohand = $oConn.Open($oConnstr) $ohand = $oConn.Open($oConnstr)^ ERRO
