I've tried this myself and didn't get a syntax error.  However, invoking
stored functions in executeBatch currently does not work.  Even though
you use "call func" in your SQL command, the PostgreSQL JDBC driver maps
this to "select func" because that is what PG requires.  Now, even
though your stored function returns void, the result of a select is
always a ResultSet, empty in this case.  But that is enough to cause
executeBatch to generate an error complaining that no return value is
allowed.

I discussed with Kris Jurka a way to address this issue, but I haven't
had time to try his solution yet.
