Agree, I had the same idea in my mind when was writing that script.
I will migrate it to TAP suite and write a review for Michael Paquier's patch.

My +1 for moving function to xlogutils.c too.
Now call to this function goes through series of callbacks so it is hard to
find it.
Personally I found it only after I have implemented same function by myself
(based on code in pg_xlogdump).

That’s interesting observation. Simon already pointed me to this problem in 2pc
replay, but I didn’t thought that it is so slow. I’m now working on that.

COMMIT/ROLLBACK. But that is a big amount of work and requires
changes to whole transaction pipeline in postgres.
Anyway I suggest that we should consider that as a separate task.

Thanks, Kevin.

Yes, this list should look like this:
Current master without 2PC: ~42 ktps
Current master with 2PC: ~22 ktps
Patched master with 2PC: ~36 ktps
And created CommitFest entry for this patch.

As we can see, kNN ordering 10 times slower than B-tree (on silly request for
R-Tree, just as example), but still 100+ times faster than full scan on this
table.

Now it supports float8, float4, int4, int2, int1. Type stored in the header of

But what we should do when arrays in different records have different numbers

Hello,
some time ago I started working on the data search system (about 100-200M of
records) with queries consisted of several diapason and equality conditions,
e.g.:
WHERE dim1 BETWEEN 128 AND 137 AND
WHERE dim2 BETWEEN 4815 AND 162342 AND
WHERE dim3 = 42
ORDER BY dim1 ASC
There are 6
101 - 129 of 129 matches
