I've pushed an updated version, with a fair amount of pending changes,
and I hope all your pending (and not redundant, by our concurrent
development), patches merged.
Yes, All the patches are merged.
There's currently 3 regression test failures, that I'll look into
tomorrow:
- partition_prune shows a few additional Heap Blocks: exact=1 lines. I'm
a bit confused as to why, but haven't really investigated yet.
- fast_default fails, because I've undone most of 7636e5c60fea83a9f3c,
I'll have to redo that in a different way.
- I occasionally see failures in aggregates.sql - I've not figured out
what's going on there.
I also observed the failure of aggregates.sql, will look into it.
Amit Khandekar said he'll publish a new version of the slot-abstraction
patch tomorrow, so I'll rebase it onto that ASAP.
OK.
Here I attached two new API patches.
1. Set New Rel File node
2. Create Init fork
The above patches are having problem and while testing it leads to crash.
Sorry for not testing earlier. The index relation also creates the NewRelFileNode,
because of moving that function as pluggable table access method, and for
Index relations, there is no tableam routine, thus it leads to crash.
So moving the storage creation methods as table access methods doesn't
work. we may need common access methods that are shared across both
table and index.
