If anybody else has got troubles with this Application:
I guess I have a Workaround with is not too hard.
In the file $INSTALL_DIR/phpgwapi/inc/class.db_pgsql.inc.php
change the function query, so that it looks like this:

/* Postgres chokes on Queries like WHERE id='' */
$Query_String = str_replace("''","'0'",$Query_String);

$this->Query_ID = @pg_Exec($this->Link_ID, $Query_String);

In other words: right before phpgroupware does a call to pg_Exec,
I replace any '' by '0' which causes Postgres to behave properly.
Thanks to Oli and Jon Pastore for ginving me the crucial hints.
