PSQLException: current transaction is aborted, commands ignored until end of transaction block

Question

I am seeing the following (truncated) stacktrace in the server.log file of JBoss 7.1.1 Final:

Caused by: org.postgresql.util.PSQLException: 
ERROR: current t         


        

Answer 1

This is very weird behavior of PostgreSQL, it is even not " in-line with the PostgreSQL philosophy of forcing the user to make everything explicit" - as the exception was caught and ignored explicitly. So even this defense does not hold. Oracle in this case behaves much more user-friendly and (as for me) correctly - it leaves a choice to the developer.
