Subject: [PATCH v6] Support run-time partition pruning for hash join

If we have a hash join with an Append node on the outer side, something
like

 Hash Join
   Hash Cond: (pt.a = t.a)
   ->  Append
         ->  Seq Scan on pt_p1 pt_1
         ->  Seq Scan on pt_p2 pt_2
         ->  Seq Scan on pt_p3 pt_3
   ->  Hash
         ->  Seq Scan on t

We can actually prune those subnodes of the Append that cannot possibly
contain any matching tuples from the other side of the join.  To do
that, when building the Hash table, for each row from the inner side we
can compute the minimum set of subnodes that can possibly match the join
condition.  When we have built the Hash table and start to execute the
Append node, we should have known which subnodes are survived and thus
can skip other subnodes.

This patch implements this idea.

I am unable to decide whether reporting the bound quals is just enough to
decide the efficiency of index without knowing the difference in the number
of index tuples selectivity and heap tuple selectivity. The difference
seems to be a better indicator of index efficiency whereas the bound quals
will help debug the in-efficiency, if any.

Also, do we want to report bound quals even if they are the same as index
conditions or just when they are different?

Thank you for your comment. After receiving your comment, I thought it would be better to also report information that would make the difference in selectivity understandable. One idea I had is to output the number of index tuples inefficiently extracted, like “Rows Removed by Filter”. Users can check the selectivity and efficiency by looking at the number.

Also, I thought it would be better to change the way bound quals are reported to align with the "Filter". I think it would be better to modify it so that it does not output when the bound quals are the same as the index conditions.

In my local PoC patch, I have modified the output as follows, what do you think?

=# EXPLAIN (VERBOSE, ANALYZE) SELECT * FROM test WHERE id1 = 1 AND id2 = 101;
                                                       QUERY PLAN

I think this is too easy to confuse with the pre-existing 'Filter'
condition, which you'll find on indexes with INCLUDE-d columns or
filters on non-index columns.
Furthermore, I think this is probably not helpful (maybe even harmful)
for index types like GIN and BRIN, where index searchkey order is
mostly irrelevant to the index shape and performance.
Finally, does this change the index AM API? Does this add another
scankey argument to ->amrescan?

>    Rows Removed by Index Filter: 499999    -- New. Output when ANALYZE option is specified

Separate from the changes to Index Cond/Index Filter output changes I
think this can be useful output, though I'd probably let the AM
specify what kind of filter data to display.
E.g. BRIN may well want to display how many ranges matched the
predicate, vs how many ranges were unsummarized and thus returned; two
conditions which aren't as easy to differentiate but can be important
debugging query performance.

Was this a test against the same dataset as the one you'd posted your
measurements of your first patchset with? The execution time seems to
have slown down quite significantly, so if the testset is the same
then this doesn't bode well for your patchset.

Why not combine them? And both call them Filter? In a sense this
filtering acts very similar to INCLUDE based filtering (for btrees at
least). Although I might be wrong about that, because when I try to
confirm the same perf using the following script I do get quite
different timings (maybe you have an idea what's going on here). But
even if it does mean something slightly different perf wise, I think
using Filter for both is unlikely to confuse anyone. Since, while
allowed, it seems extremely unlikely in practice that someone will use
the same column as part of the indexed columns and as part of the
INCLUDE-d columns (why would you store the same info twice).

It does not really behave similar: index scan keys (such as the
id3=101 scankey) don't require visibility checks in the btree code,
while the Filter condition _does_ require a visibility check, and
delegates the check to the table AM if the scan isn't Index-Only, or
if the VM didn't show all-visible during the check.

Furthermore, the index could use the scankey to improve the number of
keys to scan using "skip scans"; by realising during a forward scan
that if you've reached tuple (1, 2, 3) and looking for (1, _, 1) you
can skip forward to (1, 3, _), rather than having to go through tuples
(1, 2, 4), (1, 2, 5), ... (1, 2, n). This is not possible for
INCLUDE-d columns, because their datatypes and structure are opaque to
the index AM; the AM cannot assume anything about or do anything with
those values.

I don't want A to to be the plan, while showing B' to the user, as the
performance picture for the two may be completely different. And, as I
mentioned upthread, the differences between AMs in the (lack of)
meaning in index column order also makes it quite wrong to generally
separate prefixes equalities from the rest of the keys.

Yeah, people don't generally include the same index column more than
once in the same index.

As you can see, there's a huge difference in performance. Putting both
non-bound and "normal" filter clauses in the same Filter clause will
make it more difficult to explain performance issues based on only the
explain output.

Any chance you could point me in the right direction for the
code/docs/comment about this? I'd like to learn a bit more about why
that is the case, because I didn't realize visibility checks worked
differently for index scan keys and Filter keys.

Does Postgres actually support this currently? I thought skip scans
were not available (yet).

Yeah, that makes sense. These specific explain lines probably
only/mostly make sense for btree. So yeah we'd want the index AM to be
able to add some stuff to the explain plan.

Fair enough, that's of course the main point of this patch in the
first place: being able to better interpret the explain plan when you
don't have access to the schema. Still I think Filter is the correct
keyword for both, so how about we make it less confusing by making the
current "Filter" more specific by calling it something like "Non-key
Filter" or "INCLUDE Filter" and then call the other something like
"Index Filter" or "Secondary Bound Filter".

This looks fine. We may highlight in the documentation that lack of Index
bound quals in EXPLAIN output indicate that they are same as Index Cond:.
Other idea is to use Index Cond and bound quals as property name but that's
too long.

I don't think we want to split these clauses. Index Cond should indicate
the conditions applied to the index scan. Bound quals should be listed
separately even though they will have an intersection with Index Cond. I am
not sure whether Index Filter is the right name, maybe Index Bound Cond:
But I don't know this area enough to make a final call.

About Rows Removed by Index Filter: it's good to provide a number when
ANALYZE is specified, but it will be also better to specify what was
estimated. We do that for (cost snd rows etc.) but doing that somewhere in
the plan output may not have a precedent. I think we should try that and
see what others think.

This can be derived by combining how Filter works (it only filters the
returned live tuples) and how Index-Only scans work (return the index
tuple, unless !ALL_VISIBLE, in which case the heap tuple is
projected). There have been several threads more or less recently that
also touch this topic and closely related topics, e.g. [0][1].

Peter Geoghegan has been working on it as project after PG17's
IN()-list improvements were committed, and I hear he has the basics
working but the further details need fleshing out.

I'm not sure how debuggable explain plans are without access to the
schema, especially when VERBOSE isn't configured, so I would be
hesitant to accept that as an argument here.

OK, I understood that it's better to only add new ones. I think "Index Filter" fits other than "Index
Bound Cond" if we introduce "Rows Removed By Index Filter".

It's interesting! It’s an idea that can be applied not only to multi-column indexes, right?
I will consider the implementation and discuss it in a new thread. However, I would like to
focus on the feature to output information about multi-column indexes at first.

Thanks! I could understand what is difference between INCLUDE based filter and index filter.

IMHO, it's nice to be able to understand the differences between each
FILTER even without the VERBOSE option. (+1 for Jelte Fennema-Nio's idea)

Even without access to the schema, it would be possible to quickly know if
the plan is not as expected, and I believe there are virtually no disadvantages
to having multiple "XXX FILTER" outputs.

If it's better to output such information only with the VERBOSE option, 
What do you think about the following idea?
* When the VERBOSE option is not specified, output as "Filter" in all cases
* When the VERBOSE option is specified, output as "Non-key Filter", "INCLUDE Filter" 
  and "Index Filter".

In addition, I think it would be good to mention the differences between each filter in 
the documentation.
