Bernd,

we are in a transition to create&fill Msg_List objects in case of an  
error
and propagate these messages to the upper layers, so that SQL and admin
statements can print a detailed description of what caused the error
somewhere in the kernel.

This transition is not finished yet, so we have still a lot of functions
that won't generate message lists and other functions ignoring or  
'eating'
message lists on their way up to the user interface.

Your fix to send the output to the message file is an eligible short  
term
workaround for hidden message lists but will not help on our long  
term goal
to increase the supportability by giving direct feedback to user  
commands.

Mit freundlichen Grüßen,

    Henrik
