I haven't see a new set of patches.  Are you intending to continue
working on this?


Looks like I'll be short on bandwidth to pursue this further, given other work commitments including upcoming Postgres-XL 10 release. While I haven't worked on the patch since April, I think it was in a pretty good shape where I left it. But it's going to be incredibly difficult to estimate the amount of further efforts required, especially with testing and validating all the use cases and finding optimisations to fix regressions in all those cases. Also, many fundamental concerns around the patch touching the core of the database engine can only be addressed if some senior hackers, like you, take serious interest in the patch. 

I'll be happy if someone wants to continue hacking the patch further and get it in a committable shape. I can stay actively involved. But TBH the amount of time I can invest is far as compared to what I could during the last cycle.

Thanks,
Pavan
