Hi Vignesh,

thanks for the ping! Most important parts of this patch set are discussed in [0]. If that patchset will be committed,
I'llwithdraw entry for this thread from commitfest. 
There's a version of Multixact-specific optimizations [1], but I hope they will not be necessary with effective caches
developedin [0]. It seems to me that most important part of those optimization is removing sleeps under SLRU lock on
standby[2] by Kyotaro Horiguchi. But given that cache optimizations took 4 years to get closer to commit, I'm not sure
wewill get this optimization any time soon... 

Thanks!

Best regards, Andrey Borodin.
