Hi,
I created a thread for this at http://stackoverflow.com/questions/1333596/postgresql-identity-in-jpa-single-table-hierarchy which details the full environment and code I was attempting to run.
Briefly my environment is:
PostgreSQL 8.3
JDBC Driver postgresql-8.4-701.jdbc4
This resulted in an error when using a JPA generation type of IDENTITY in a single table inheritance hierarchy. The discriminator was a String but was trying to be parsed as a long by the framework. For demo purposes when using a String that was a parseable value e.g. 123 the error did not occur but the framework believed the discriminator value was the primary key.
I switched the JDBC driver to postgresql-8.3-605.jdbc4.jar and the problem doesn't seem to occur.
I'm running Java 6 so believed the latest driver to be the correct one even though I'm not running the 8.4 server.
Please let me know if you need any further information or if I can assist in fixing the issue.
Kind regards,
