The version 5.0 of HOT WIP patch is posted on pgsql-patches. This fixes the VACUUM FULL issue with HOT. In all the earlier versions, I'd disabled VACUUM FULL.
When we move the HOT-chain, we move the chains but don't carry the HOT_UPDATED or HEAP_ONLY flags and insert as many index entries as there are tuples in the chain. IOW the HOT-update is actually turned into a COLD chain. Apart from this, I'd to make some changes to the VACUUM FULL code so that the number of indexed tuples is counted correctly. With HOT, whenever a HEAP_ONLY tuple is moved, an additional index entry is generated and this needs to be taken into account. Please let me know comments/suggestions.
