Hi folks-
Sorry to pull things backward here, but having set my web user up with sane
grants, I'm a bit more concerned about the performance issues- I can't find
this method in the Sun JDBC spec, so I'm assuming it is PostgreSQL-specific?
Is this the correct way to use it:
 PreparedStatement ps = db.prepareStatement("select foo from bar where foo
like ?");
 ps.setUseServerPrepare(true);
 .
 .
 .
 ps.setString(1, "fubar");
 ResultSet rs = ps.executeQuery();
(Where the first two lines get executed once when I init my app, but the
last two lines may get executed any number of times.)
Also- is the javadoc for postgresql JDBC online anywhere for folks like
myself who just download the current stable jarfile?
Thanks
