Hi hackers!

Here's some update on the subject - I've made a branch based on master from
28/11 and introduced 64-bit TOAST value ID there. It is not complete now but
is already working and has some features:
- extended structure for TOAST pointer (varatt_long_external) with 64-bit
TOAST value ID;
- individual ID counters for each TOAST table, being cached for faster
access
and lookup of maximum TOAST ID in use after server restart.
