> How did you build the tid store and test on v15? I first tried to apply v15-0009-PoC-lazy-vacuum-integration.patch,
whichconflicts with vacuum now, so reset all that, but still getting build errors because the tid store types and
functionshave changed.
 

I applied v26-0008-Add-TIDStore-to-store-sets-of-TIDs-ItemPointerDa.patch
on top of v15 radix tree and changed the TidStore so that it uses v15
(non-templated) radixtree. That way, we can test TidStore using v15
radix tree. I've attached the patch that I applied on top of
v26-0008-Add-TIDStore-to-store-sets-of-TIDs-ItemPointerDa.patch.
