Hello! I need to use the 'age (xid)' function, but I have noticed that it is deprecated without a clear alternative. I know that xid is also kinda deprecated, so it makes sense not to use it. I can get xid8 from 'pg_current_xact_id()', which replaced 'txid_current()', but cannot use it right away with 'age'.
I can cast xid8 that I've got to xid and pass to 'age', but 1) I have no idea if it's the right way, i.e. it's promised to work or will work anyway by accident, 2) 'age' is anyway deprecated. I can re-implement 'age' by myself. It's (mostly) a subtraction after all. But it would mean that I inline implementation in place of "api" function call which is not always a great idea. Could anyone advise, please? Kind regards, Ivan
