Hi,

I tried to use the @returnInsert annotation

@ReturnInsert(returnOnly=true) 
protected Timestamp insertdate;

and got this exception:

Exception [EclipseLink-193] (Eclipse Persistence Services - 1.2.0.v20091016-r5565): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: There is no custom [InsertObjectQuery] set, but ReturningPolicy contains field(s) to be returned and [PostgreSQLPlatform] doesnt support generating call with returning.
Descriptor: RelationalDescriptor(ppd.model.entities.DVHist --> [DatabaseTable(DV_HIST)])
	at org.eclipse.persistence.exceptions.DescriptorException.noCustomQueryForReturningPolicy(DescriptorException.java:1855)
	at org.eclipse.persistence.descriptors.ReturningPolicy.validationAfterDescriptorInitialization(ReturningPolicy.java:871)

	at org.eclipse.persistence.descriptors.ClassDescriptor.validateAfterInitialization(ClassDescriptor.java:5222)
	at org.eclipse.persistence.descriptors.ClassDescriptor.postInitialize(ClassDescriptor.java:3218)

I'd like to know how I can make this work with PostgreSQL

Thanks

Returning using the "RETURNING" clause is currently only supported on Oracle. For other database native SQL is required for the INSERT/UPDATE to allow returning.

PostgreSQL does seem to have support for the "RETURNING" clause though, so please log a bug to have this support added.

You can customize your own subclass of the PostgreSQLPlatform yourself to add returning support. You need to override the methods, buildCallWithReturning and canBuildCallWithReturning.

I will looking into adding this support in the 2.0 stream.
