Hello.

I've tried to use Character to fill "char" column, e.g. like in the next
test:
-----
con.createStatement().execute("create table tst(tcol \"char\")");
PreparedStatement stmt = con.prepareStatement("insert into tst(tcol)
values(?)");
stmt.setObject(1, 'c');
stmt.executeUpdate();
-----
and got
Exception in thread "main" org.postgresql.util.PSQLException: Can't infer
the SQL type to use for an instance of java.lang.Character. Use setObject()
with an explicit Types value to specify the type to use. at
org.postgresql.jdbc2.AbstractJdbc2Statement.setObject(AbstractJdbc2Statement.java:1740)


with 8.3-603.jdbc4 driver.
May be it would be reasonable to treat Character like String of size 1?
