What escape sequence is that? We could look at implementing it.

I see no reason why the WHERE clause would alter the type of a result
column. Checking:

Object o = rs.getObject(col);
if (o instanceof PGobject) {
System.err.println(((PGobject)o).getType());
System.err.println(((PGobject)o).getValue());
}

or similar would tell you what the returned type was.
