The freeze map uses an additional bit in the vm, and pg_upgrade would
take care of the conversion
Hi,
one of the major enhancements in 96 is skipping completely frozen pages in
vacuum freeze. I assume that requires a special bit on the page.
If I upgrade from 93 using pg_upgrade, that is re-using the data files, can
it still do that? Or do I have to recreate the table?
Thanks,
Torsten
