In Postgresql 9.0, the default value for bytea_output changed from 'escape' to 'hex'. I've had an issue where the value written in to the db was read out incorrectly due to this. To fix the problem in PGAdmin3, right click on your database, and select the 'Properties' context menu option. In the properties window that pops up, select the 'Variables' tab, and set the value appropriately.
This framework is a plugin for the WebObjects
JDBCAdaptor so that it is able to communicate with a PostgreSQL database server. The easiest way to get the
PostgresPlugin.framework is to install Project Wonder. Otherwise, you can download the built frameworks from the mDimension Hudson build server (either Wonder53 or Wonder54 Wonder for WebObjects 5.3 or Wonder of WebObjects 5.4), extract the
PostgresqlPlugIn.framework, and place it in
~/Library/Frameworks. You must add the
PostgresPlugin.framework to your application's build path so that it is able to find the plugin.
