Hi,

importing data from Confluence Version 2.5.4 into 3.0.2 the Importer gives me the following error:

Import failed. Hibernate operation: could not insert: com.atlassian.confluence.pages.Page#19202739; uncategorized SQLException for SQL []; SQL state [25P02]; error code [0]; ERROR: current transaction is aborted, commands ignored until end of transaction block; nested exception is org.postgresql.util.PSQLException: ERROR: current transaction is aborted, commands ignored until end of transaction block

and pg_log says:

The restore file is a daily backup with attachments stripped.
Database collation is UTF-8. I got no further ideas where to look for so i reckon this a bug (maybe in some rare setups).
An empty installation with the wizard runs fine without an error.

Thank You.

EDIT:
Now I've tried several combinations. From standalone version w/ Tomcat and JDBC connection to the Postgres DB on the target remote server as well as the embedded derby database. None of them are working.
