> SELECT datname,pg_encoding_to_char(encoding) FROM > pg_database; Thanks for the suggestion Kris. I also got some help from Barry. The problem is that the encoding in the db was ascii, which causes a discrepency between Java string lengths and the string lengths in the db. The solution is to drop and recreate the db using unicode encoding. One conclusion from this is that, as a Java developer, unless you are absolutely sure that all the strings you are dealing with really are ascii, you should be sure that the db has unicode encoding. Java does not internally use ascii for anything. Everything in Java is UTF-16, so external storage that Java uses should be able to represent the full range of UTF characters. I think this would make a good entry in the JDBC FAQ: "Always use Unicode encoding when using the JDBC unless you are sure that you are only dealing with ASCII."
