I imagine you're working on the Andres's comments and you already notice this, but v1 patch cannot be applied to HEAD. For the convenience of other reviewers, I marked it 'Waiting on Author'.
Thanks for letting me know. I rebased the patch. PFA new version.

Hi,
Have you checked what the source of the remaining allocations in CacheMemoryContext are?
It's mostly typecache, around 2K. Do you think typecache also needs a separate context?
Given the size of both CatCacheMemoryContext and RelCacheMemoryContext in a new backend, I think it might be worth using non-default aset parameters. A bit ridiculous to increase block sizes from 8k upwards in every single connection made to postgres ever.
Considering it starts from ~262K, what would be better for init size? 256K?

We typically use (void) to differentiate from an older way of function declarations that didn't have argument types.
Done.

I wish we just made sure that cache memory context were created in the right place, instead of spreading this check everywhere...
That would be nice. Do you have a suggestion about where that right place would be?
I'd just delete these comments, they're just pointlessly restating the code.
