Hmm, looking at the PSQLException source code, I don't think the driver
has ever set the vendor-specific error code that getErrorCode() returns.
I tested the snippet you posted with server 8,4 and 9.2, and with jdbc
driver 8.4 and 8.2, and saw no difference; getErrorCode() always returned 0.
You should be using getSQLState() instead. The "23505" sqlstate is
defined by the SQL standard, so if the other DBMS' you're supporting
follow the spec on that, you won't even need any vendor-specific code there.
