Of course the liabilities are associated with pension payments made into government that very efficiently fund government expenditure and are still receiving ongoing payments (overall currently running in profit).
What does "they are managed" mean beyond that there are (regularly changing) estimate of the outstanding pension liabilities?
With the exception of the local government scheme all major public sector pension schemes (and the State pension) are unfunded i.e..they are paid for out of current income not out of assets accumulated by the pension beneficiaries or the State at large. They promise defined benefits but deppend on difficult to forecast surest incomes to pay those benefits.
How does that differ from "a scheme that does not invest the money it receives but simply pays existing investors out of the contributions from new investors."?

Firstly these 'errors' are overstated as the best guestimates are already included in the recent calculations (and recently changed contributions and benefits) so are already factored in and secondly any future changes will require even more adjustments one way or another.

Just to clarify, my comment on the cause of underfunding were with relation to private secotr pensions which is what you seemed to be referring to. You seem to be saying that because these funding shortages have now been incorporated into current calculations they are "overstated". Why?
It became apparent over the past decade that for a number of reasons the private secor pension sector was becoming underfunded and needed restructuring. Simply saying that this has been acknowledged and partly executed doesn't change or lessen the extent of the causes of the underfunding.
