I am still working on redesigning the patch set to avoid the pointer
redirection and the callbacks assigned to the vartags.
One thing that stands out for me is that I am going to need the oid8
data type anyway, to be store the 8-byte values in the catalogs, with
a C type to mark some of the TOAST apis with it across the board, so I
would like to apply that to move this part out of the way (0001 only)
and move the needle. If there are any objections to that, please feel
free.
