原因

The PostgreSQL 8.x JDBC drivers that ship with Confluence are not compatible with PostgreSQL 9.x. The underlying cause is a change to PostgreSQL which has modified the bytea_output data type.

This change affects Confluence's ability to store plugin binaries in the plugindata table in the database when installing a new plugin.

ソリューション

Confluence 4.0 and later contains the updated PostgreSQL 9.x JDBC drivers which fixes this problem.

If you are running an earlier version of Confluence, you can upgrade to the latest PostgreSQL JDBC drivers by replacing the existing driver JAR file in Confluence's WEB-INF/lib/ directory. The driver version 9.0-801.jdbc3 does not suffer from this problem.
