I have picked out one of the statements that suffered from this and sanitized the logfile.

   http://sql-workbench.net/pg_jdbc_94.log

The complete statement is at the top of the file and in the messages themselves,
I have replaced each occurrence of the statement with "select ...."

The interesting thing (at least for me) is that the first few executions of the
server side statement have pretty much the same runtime as the ones before the prepare.
And then suddenly the runtime shoots through the rough going up from 1ms to 40ms or even 60ms
