I was wondering about this point - might it not be just as reasonable
for the copied file to *be* an exact image of pg_control? Then a very
simple variant of pg_controldata (or maybe even just adding switches to
pg_controldata itself) would enable the relevant info to be extracted
P.s : would love to be that volunteer - however up to the eyeballs in
Business Objects (cringe) and Db2 for the next week or so....
