+/*
+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 4/5] BRIN minmax-multi indexes
@ 2020-09-12 13:07  Tomas Vondra <tomas.vondra@postgresql.org>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2020-09-12 13:07 UTC (permalink / raw)

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.

+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 5/6] BRIN minmax-multi indexes
@ 2020-09-12 13:07  Tomas Vondra <tomas.vondra@postgresql.org>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2020-09-12 13:07 UTC (permalink / raw)

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.

+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 5/6] BRIN minmax-multi indexes
@ 2020-09-12 13:07  Tomas Vondra <tomas.vondra@postgresql.org>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2020-09-12 13:07 UTC (permalink / raw)

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.

+/*
+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 7/8] BRIN minmax-multi indexes
@ 2020-12-16 20:32  Tomas Vondra <tomas.vondra@postgresql.org>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2020-12-16 20:32 UTC (permalink / raw)

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.

+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 5/6] BRIN minmax-multi indexes
@ 2020-12-16 20:32  Tomas Vondra <tomas.vondra@postgresql.org>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2020-12-16 20:32 UTC (permalink / raw)

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.

+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 6/8] BRIN minmax-multi indexes
@ 2021-02-03 18:00  Tomas Vondra <tomas@2ndquadrant.com>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2021-02-03 18:00 UTC (permalink / raw)

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.

+ *
+ *   [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.

* [PATCH 5/6] BRIN minmax-multi indexes
@ 2021-02-03 18:00  Tomas Vondra <tomas@2ndquadrant.com>

From: Tomas Vondra @ 2021-02-03 18:00 UTC (permalink / raw)

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 multi-minmax 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 75% 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.
+ *

+ * are of equal (or very similar) length.
+ *
+ * Consider for example points 1, 2, 3, .., 64, which have gaps of the

* [PATCH 5/9] BRIN minmax-multi indexes
@ 2021-02-03 18:00  Tomas Vondra <tomas@2ndquadrant.com>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2021-02-03 18:00 UTC (permalink / raw)

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.

+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

+ * Consider for example points 1, 2, 3, .., 64, which have gaps of the

* [PATCH 5/9] BRIN minmax-multi indexes
@ 2021-02-03 18:00  Tomas Vondra <tomas@2ndquadrant.com>

From: Tomas Vondra @ 2021-02-03 18:00 UTC (permalink / raw)

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.

+ * brin_minmax_multi.c
+ *		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 multi-minmax 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 75% 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.
+ *

* [PATCH 6/8] BRIN minmax-multi indexes
@ 2021-03-21 23:24  Tomas Vondra <tomas.vondra@postgresql.org>
  0 siblings, 0 replies; 12+ messages in thread

From: Tomas Vondra @ 2021-03-21 23:24 UTC (permalink / raw)

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.

+ * Implements a variant of minmax opclass, where the summary is composed of
+ * multiple smaller intervals. This allows us to handle outliers, which
+ * usually make 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 32 (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.
+ *
+ * The compactions (reducing the number of values) is fairly expensive, as
+ * it requires calling the distance functions, sorting etc. So when building
+ * the summary, we use a significantly larger buffer, and only enforce the
+ * exact limit at the very end. This improves performance, and it also helps
+ * with building better ranges (due to the greedy approach).

* [PATCH v1] Fix floating-point noise in pg_stat_us_to_ms()
@ 2026-06-29 06:31  Bertrand Drouvot <bertranddrouvot.pg@gmail.com>

From: Bertrand Drouvot @ 2026-06-29 06:31 UTC (permalink / raw)

Multiplying by 0.001 can produce trailing-digit noise in displayed
values (for example 0.009000000000000001 instead of 0.009, should extra_float_digits
not being set to 0) because 0.001 cannot be represented exactly in binary floating
point.

Use division by 1000.0 instead as it is the most common way to deal with such
computation in the code tree.
