Hi,

Here is an updated version of the patch series.

It fixes the assert failure (just remove the multiplication from it) and
adds a simple regression test that exercises this.

Based on the discussion so far, I've decided to keep just the new
signature of the consistent function. That's a bit simpler than having
to support both 3 and 4 parameters, and it would not deal with the NULL
changes anyway (mostly harmless code duplication, but still). I've also
realized the API documentation in SGML needs updating.

At this point, I think 0001-0006 parts are mostly committable.

As for the remaining two parts, the one dealing with correlation may not
be strictly necessary, but not having it (or something like it) may
result in not picking the BRIN index in some cases.

But maybe it's not a major problem. I tried the example from [1] but it
no longer triggers the issue for me - I'm not entirely sure why, but the
costing changed for some reason. It used to look like this:

                             QUERY PLAN
------------------------------------------------------------------------
  Bitmap Heap Scan on t  (cost=5553.07..174800.78 rows=10 width=4)
                         (actual time=7.790..27.585 rows=10 loops=1)
    Recheck Cond: (a = 10000)
    Rows Removed by Index Recheck: 224182
    Heap Blocks: lossy=992
    ->  Bitmap Index Scan on t_a_idx
          (cost=0.00..5553.06 rows=9999977 width=0)
          (actual time=7.006..7.007 rows=9920 loops=1)
          Index Cond: (a = 10000)
  Planning Time: 0.052 ms
  Execution Time: 27.658 ms
(8 rows)

but now I'm getting this:

                             QUERY PLAN
------------------------------------------------------------------------
 Bitmap Heap Scan on t  (cost=5546.22..97469.16 rows=10 width=4)
                        (actual time=5.264..32.051 rows=10 loops=1)
   Recheck Cond: (a = 10000)
   Rows Removed by Index Recheck: 314582
   Heap Blocks: lossy=1392
   ->  Bitmap Index Scan on t_a_idx
         (cost=0.00..5546.22 rows=3813995 width=0)
         (actual time=2.534..2.536 rows=13920 loops=1)
         Index Cond: (a = 10000)
 Planning Time: 0.052 ms
 Execution Time: 32.095 ms
(8 rows)

The index scan cost is about the same, but the heap scan is about half
the cost. The row estimates are a bit different, perhaps that's related.
The seqscan cost (169248) and duration (~500ms) is still about the same,
but so now we still pick the bitmap heap scan. Not sure we can rely on
this, though. Would be quite sad if we had new improved opclasses but
the planner often decided not to use them.


While playing with this, I discovered another weirdness - consider this
example (a more complete reproducer.sql script attached). If you try it
without the 0008 part, you'll get this:

init
----

  create table t (a int, b bigint, c text) with (fillfactor = 50);

  insert into t select
      1000000 * random(),
      1000000 * random(),
      md5((1000000 * random())::int::text)
  from generate_series(1,1000000) s(i);

  create index bloom_a_idx on t using brin
    (a int4_bloom_ops(n_distinct_per_range=6000));

  analyze t;


query
-----

  explain select * from t where a = 1000;

                              QUERY PLAN
  -----------------------------------------------------------------
   Bitmap Heap Scan on t  (cost=660.03..14000.00 rows=2 width=45)
     Recheck Cond: (a = 1000)
     ->  Bitmap Index Scan on bloom_a_idx
          (cost=0.00..660.03 rows=6135 width=0)
           Index Cond: (a = 1000)
  (4 rows)


So far so good - we're using the right index.


create another index (regular minmax on random data)
----------------------------------------------------

  create index brin_idx on t using brin (a);

  analyze t;


query (again)
-------------

explain select * from t where a = 1000;

                        QUERY PLAN
  ------------------------------------------------------
   Seq Scan on t  (cost=0.00..33334.00 rows=2 width=45)
     Filter: (a = 1000)
  (2 rows)

Umm, what? We've created an index, we don't pick it, but it somehow
blocks us from using the right index? So we end up with a sequential
scan, which is much more expensive (both in terms of cost and duration)
than using the bloom index.

Turns out this is due to how choose_bitmap_and eliminates index paths
with the same set of clauses - it simply compares the cost for reading
the index itself. And the bloom filter is larger than plain minmax,
hence it loses. But this entirely ignores the cost increase at the heap
scan level - the minmax index is absulutely terrible, and it loses not
just to bloom index (which we've discarded already) but also to seqscan.

I had an idea of tweaking choose_bitmap_and to consider both the cost
and selectivity (similarly to how add_path considers statup/total cost),
and that did indeed resolve this particular case. This is what the 0008
part does.

But it may also have negative consequence, as demonstrated by the
reproducer2.sql script. So maybe the logic would need to be more
complicated. Or maybe there's no reliable solution, considering how
tricky/unreliable BRIN estimates are.

That being said, I don't think this is something we need to solve here,
and it may not actually be an issue at all. For this to happen there
need to be a terrible index on the same attribute (like the minmax index
in the example above). But why keeping such index anyway? Dropping it
would make the issue go away. If we have two indexes that both perform
reasonably (say, bloom and minmax-multi), the consequences are not that
bad. so this is interesting, but probably fine.

Subject: [PATCH 2/8] Pass all scan keys to BRIN consistent function at once

Passing all scan keys to the BRIN consistent function at once may allow
elimination of additional ranges, which would be impossible when only
passing individual scan keys.

This modifies the existing BRIN opclasses (minmax, inclusion) although
those don't really benefit from this change. The primary purpose of this
is to allow future opclases to benefit from seeing all keys at once.

This does break existing BRIN opclasses, because the signature of the
consistent function changed. We might support both variants (with 3 and
4 parameters), but that seems pointless - the changes to NULL handling
likely require updates too. So better to make the failure clear. Also,
we're not aware of any out-of-core opclasses - there may be some, but
probably not many.

From 3b3ee67673223d7c5574d2c68337720f6829acb7 Mon Sep 17 00:00:00 2001
From: Tomas Vondra <tomas@2ndquadrant.com>
Date: Tue, 2 Mar 2021 19:27:48 +0100
Subject: [PATCH 3/8] Move IS [NOT] NULL handling from BRIN support functions

The handling of IS [NOT] NULL clauses is independent of an opclass, and
most of the code was exactly the same in both minmax and inclusion. So
instead move the code from support procedures to the AM methods etc.

This simplifies the code quite a bit - especially the support procedures
quite a bit, as they don't need to care about NULL values and flags at
all. It also means the IS [NOT] NULL clauses can be evaluated without
invoking the support procedure at all.

Subject: [PATCH 4/8] Optimize allocations in bringetbitmap

The bringetbitmap function allocates memory for various purposes, which
may be quite expensive, depending on the number of scan keys. Instead of
allocating them separately, allocate one bit chunk of memory an carve it
into smaller pieces as needed - all the pieces have the same lifespan,
and it saves quite a bit of CPU and memory overhead.

Subject: [PATCH 5/8] BRIN bloom indexes

Adds a BRIN opclass using a Bloom filter to summarize the range. BRIN
indexes using the new opclasses only allow equality queries, but that
works for data like UUID, MAC addresses etc. for which range queries are
not very common (and the data look random, making BRIN minmax indexes
inefficient anyway).

BRIN bloom opclasses allow specifying the usual Bloom parameters, like
expected number of distinct values (in the BRIN range) and desired
false positive rate.

The opclasses store 32-bit hashes of the values, not the raw indexed
values. This assumes the hash functions for data types has low number
of collisions, good performance etc. Collisions are not a huge issue
though, because the number of values in a BRIN ranges is fairly small.

+ * brin_bloom.c
+ *		Implementation of Bloom opclass for BRIN
+ *
+ * Portions Copyright (c) 1996-2017, PostgreSQL Global Development Group
+ * Portions Copyright (c) 1994, Regents of the University of California
+ *
+ *
+ * A BRIN opclass summarizing page range into a bloom filter.
+ *
+ * Bloom filters allow efficient testing whether a given page range contains
+ * a particular value. Therefore, if we summarize each page range into a
+ * bloom filter, we can easily and cheaply test whether it contains values
+ * we get later.
+ *
+ * The index only supports equality operators, similarly to hash indexes.
+ * BRIN bloom indexes are however much smaller, and support only bitmap
+ * scans.
+ *
+ * Note: Don't confuse this with bloom indexes, implemented in a contrib
+ * module. That extension implements an entirely new AM, building a bloom
+ * filter on multiple columns in a single row. This opclass works with an
+ * existing AM (BRIN) and builds bloom filter on a column.
+ *
+ *
+ * values vs. hashes
+ * -----------------
+ *
+ * The original column values are not used directly, but are first hashed
+ * using the regular type-specific hash function, producing a uint32 hash.
+ * And this hash value is then added to the summary - i.e. it's hashed
+ * again and added to the bloom filter.
+ *
+ * This allows the code to treat all data types (byval/byref/...) the same
+ * way, with only minimal space requirements, because we're working with
+ * hashes and not the original values. Everything is uint32.
+ *
+ * Of course, this assumes the built-in hash function is reasonably good,
+ * without too many collisions etc. But that does seem to be the case, at
+ * least based on past experience. After all, the same hash functions are
+ * used for hash indexes, hash partitioning and so on.
+ *
+ *
+ * sizing the bloom filter
+ * -----------------------
+ *
+ * Size of a bloom filter depends on the number of distinct values we will
+ * store in it, and the desired false positive rate. The higher the number
+ * of distinct values and/or the lower the false positive rate, the larger
+ * the bloom filter. On the other hand, we want to keep the index as small
+ * as possible - that's one of the basic advantages of BRIN indexes.
+ *
+ * Although the number of distinct elements (in a page range) depends on
+ * the data, we can consider it fixed. This simplifies the trade-off to
+ * just false positive rate vs. size.
+ *
+ * At the page range level, false positive rate is a probability the bloom
+ * filter matches a random value. For the whole index (with sufficiently
+ * many page ranges) it represents the fraction of the index ranges (and
+ * thus fraction of the table to be scanned) matching the random value.
+ *
+ * Furthermore, the size of the bloom filter is subject to implementation
+ * limits - it has to fit onto a single index page (8kB by default). As
+ * the bitmap is inherently random, compression can't reliably help here.
+ * To reduce the size of a filter (to fit to a page), we have to either
+ * accept higher false positive rate (undesirable), or reduce the number
+ * of distinct items to be stored in the filter. We can't alter the input
+ * data, of course, but we may make the BRIN page ranges smaller - instead
+ * of the default 128 pages (1MB) we may build index with 16-page ranges,
+ * or something like that. This does help even for random data sets, as
+ * the number of rows per heap page is limited (to ~290 with very narrow
+ * tables, likely ~20 in practice).
+ *
+ * Of course, good sizing decisions depend on having the necessary data,
+ * i.e. number of distinct values in a page range (of a given size) and
+ * table size (to estimate cost change due to change in false positive
+ * rate due to having larger index vs. scanning larger indexes). We may
+ * not have that data - for example when building an index on empty table
+ * it's not really possible. And for some data we only have estimates for
+ * the whole table and we can only estimate per-range values (ndistinct).
+ *
+ * Another challenge is that while the bloom filter is per-column, it's
+ * the whole index tuple that has to fit into a page. And for multi-column
+ * indexes that may include pieces we have no control over (not necessarily
+ * bloom filters, the other columns may use other BRIN opclasses). So it's
+ * not entirely clear how to distrubute the space between those columns.
+ *
+ * The current logic, implemented in brin_bloom_get_ndistinct, attempts to
+ * make some basic sizing decisions, based on the size of BRIN ranges, and
+ * the maximum number of rows per range.

Subject: [PATCH 6/8] BRIN minmax-multi indexes

Adds a BRIN minmax-multi opclass, summarizing each range into a list of
intervals, allowing more efficient handling of cases where the minmax
opclasses quickly degrade.

Instead of representing each range with a single interval, minmax-multi
opclasses store a list of intervals and points. This allows effective
handling of outliers and poorly correlated values.

The number of intervals/points per range may be configured using an
opclass parameter values_per_range. When building the summary, the
interval are merged based on distance, determined by the new support
BRIN procedure.

+ *		Implementation of Multi Min/Max opclass for BRIN

+ * Portions Copyright (c) 1996-2017, PostgreSQL Global Development Group
+ * Portions Copyright (c) 1994, Regents of the University of California
+ *
+ *
+ * Implements a variant of minmax opclass, where the summary is composed of
+ * multiple smaller intervals. This allows us to handle outliers, which
+ * usually makes the simple minmax opclass inefficient.
+ *
+ * Consider for example page range with simple minmax interval [1000,2000],
+ * and assume a new row gets inserted into the range with value 1000000.
+ * Due to that the interval gets [1000,1000000]. I.e. the minmax interval
+ * got 1000x wider and won't be useful to eliminate scan keys between 2001
+ * and 1000000.
+ *
+ * With minmax-multi opclass, we may have [1000,2000] interval initially,
+ * but after adding the new row we start tracking it as two interval:
+ *
+ *   [1000,2000] and [1000000,1000000]
+ *
+ * This allow us to still eliminate the page range when the scan keys hit
+ * the gap between 2000 and 1000000, making it useful in cases when the
+ * simple minmax opclass gets inefficient.
+ *
+ * The number of intervals tracked per page range is somewhat flexible.
+ * What is restricted is the number of values per page range, and the limit
+ * is currently 64 (see values_per_range reloption). Collapsed intervals
+ * (with equal minimum and maximum value) are stored as a single value,
+ * while regular intervals require two values.
+ *
+ * When the number of values gets too high (by adding new values to the
+ * summary), we merge some of the intervals to free space for more values.
+ * This is done in a greedy way - we simply pick the two closest intervals,
+ * merge them, and repeat this until the number of values to store gets
+ * sufficiently low (below 50% of maximum values), but that is mostly
+ * arbitrary threshold and may be changed easily).
+ *
+ * To pick the closest intervals we use the "distance" support procedure,
+ * which measures space between two ranges (i.e. length of an interval).
+ * The computed value may be an approximation - in the worst case we will
+ * merge two ranges that are slightly less optimal at that step, but the
+ * index should still produce correct results.

+ *
+ * Returns the number of result ranges.
+ *
+ * We simply use the global min/max and then add boundaries for enough
+ * largest gaps. Each gap adds 2 values, so we simply use (target/2-1)
+ * distances. Then we simply sort all the values - each two values are
+ * a boundary of a range (possibly collapsed).
+ *
+ * XXX Some of the ranges may be collapsed (i.e. the min/max values are
+ * equal), but we ignore that for now. We could repeat the process,
+ * adding a couple more gaps recursively.
+ *
+ * XXX The ranges to merge are selected solely using the distance. But
+ * that may not be the best strategy, for example when multiple gaps
+ * are of equal (or very similar) length.
+ *
+ * Consider for example points 1, 2, 3, .., 64, which have gaps of the
+ * same length 1 of course. In that case we tend to pick the first
+ * gap of that length, which leads to this:
+ *
+ *    step 1:  [1, 2], 3, 4, 5, .., 64
+ *    step 2:  [1, 3], 4, 5,    .., 64
+ *    step 3:  [1, 4], 5,       .., 64
+ *    ...
+ *
+ * So in the end we'll have one "large" range and multiple small points.
+ * That may be fine, but it seems a bit strange and non-optimal. Maybe
+ * we should consider other things when picking ranges to merge - e.g.
+ * length of the ranges? Or perhaps randomize the choice of ranges, with
+ * probability inversely proportional to the distance (the gap lengths
+ * may be very close, but not exactly the same).

+ * tie-break, or by adding random noise to the actual distance.
