comments on prepared transactions ...

i had to deal with oracle in the past couple of days (*mega sigh*)
i have seen a very interesting feature which would make sense for 
PostgreSQL users.

currently we have:

test=# \h PREPARE TRANSACTION
Command:     PREPARE TRANSACTION
Description: prepare the current transaction for two-phase commit
Syntax:
PREPARE TRANSACTION transaction_id

in oracle it is possible to comment transactions:

COMMIT COMMENT 'ORA-2PC-CRASH-TEST-n';

if we added the possibility to comment prepared transactions it would be 
far easier for DBAs to find out what to do with prepared transactions 
once something has gone wrong (at least if an application adds some 
useful data to the comment). usually when the DBA has to fix something 
it has to be done FAST - some additional info would definitely help here ...

what do people think about this?
best regards,
    hans
