+ * This can sometimes result in so->keyData[] keys that aren't even in index
+ * attribute order (if the qual involves multiple attributes). The scan's
+ * required keys will still be in attribute order, though, so it can't matter.

* Examine the scan keys to discover where we need to start the scan.
+ * The selected scan keys (at most one per index column) are remembered by
+ * storing their addresses into the local startKeys[] array. The final
+ * startKeys[] entry's strategy is set in strat_total. (Actually, there
+ * are a couple of cases where we force a less/more restrictive strategy.)
*
- * We want to identify the keys that can be used as starting boundaries;
- * these are =, >, or >= keys for a forward scan or =, <, <= keys for
- * a backwards scan. We can use keys for multiple attributes so long as
- * the prior attributes had only =, >= (resp. =, <=) keys. Once we accept
- * a > or < boundary or find an attribute with no boundary (which can be
- * thought of as the same as "> -infinity"), we can't use keys for any
- * attributes to its right, because it would break our simplistic notion
- * of what initial positioning strategy to use.
+ * We must use the key that was marked required (in the direction opposite
+ * our own scan's) during preprocessing. Each index attribute can only
+ * have one such required key. In general, the keys that we use to find
+ * an initial position when scanning forwards are the same keys that end
+ * the scan on the leaf level when scanning backwards (and vice-versa).
*
* When the scan keys include cross-type operators, _bt_preprocess_keys
- * may not be able to eliminate redundant keys; in such cases we will
- * arbitrarily pick a usable one for each attribute. This is correct
- * but possibly not optimal behavior. (For example, with keys like
- * "x >= 4 AND x >= 5" we would elect to scan starting at x=4 when
- * x=5 would be more efficient.) Since the situation only arises given
- * a poorly-worded query plus an incomplete opfamily, live with it.
+ * may not be able to eliminate redundant keys; in such cases it will
+ * arbitrarily pick a usable key for each attribute (and scan direction),
+ * ensuring that there is no more than one key required in each direction.
+ * We stop considering further keys once we reach the first nonrequired
+ * key (which must come after all required keys), so this can't affect us.
+ *
+ * The required keys that we use as starting boundaries have to be =, >,
+ * or >= keys for a forward scan or =, <, <= keys for a backwards scan.
+ * We can use keys for multiple attributes so long as the prior attributes
+ * had only =, >= (resp. =, <=) keys. These rules are very similar to the
+ * rules that preprocessing used to determine which keys to mark required.
+ * We cannot always use every required key as a positioning key, though.
+ * Skip arrays necessitate independently applying our own rules here.
+ * Skip arrays are always generally considered = array keys, but we'll
+ * nevertheless treat them as inequalities at certain points of the scan.
+ * When that happens, it _might_ have implications for the number of
+ * required keys that we can safely use for initial positioning purposes.
*
- * When both equality and inequality keys appear for a single attribute
- * (again, only possible when cross-type operators appear), we *must*
- * select one of the equality keys for the starting point, because
- * _bt_checkkeys() will stop the scan as soon as an equality qual fails.
- * For example, if we have keys like "x >= 4 AND x = 10" and we elect to
- * start at x=4, we will fail and stop before reaching x=10. If multiple
- * equality quals survive preprocessing, however, it doesn't matter which
- * one we use --- by definition, they are either redundant or
- * contradictory.
+ * For example, a forward scan with a skip array on its leading attribute
+ * (with no low_compare/high_compare) will have at least two required scan
+ * keys, but we won't use any of them as boundary keys during the scan's
+ * initial call here. Our positioning key during the first call here can
+ * be thought of as representing "> -infinity". Similarly, if such a skip
+ * array's low_compare is "a > 'foo'", then we position using "a > 'foo'"
+ * during the scan's initial call here; a lower-order key such as "b = 42"
+ * can't be used until the "a" array advances beyond MINVAL/low_compare.
*
- * In practice we rarely see any "attribute boundary key gaps" here.
- * Preprocessing can usually backfill skip array keys for any attributes
- * that were omitted from the original scan->keyData[] input keys. All
- * array keys are always considered = keys, but we'll sometimes need to
- * treat the current key value as if we were using an inequality strategy.
- * This happens with range skip arrays, which store inequality keys in the
- * array's low_compare/high_compare fields (used to find the first/last
- * set of matches, when = key will lack a usable sk_argument value).
- * These are always preferred over any redundant "standard" inequality
- * keys on the same column (per the usual rule about preferring = keys).
- * Note also that any column with an = skip array key can never have an
- * additional, contradictory = key.
+ * On the other hand, if such a skip array's low_compare was "a >= 'foo'",
+ * then we _can_ use "a >= 'foo' AND b = 42" during the initial call here.
+ * A subsequent call here might have us use "a = 'fop' AND b = 42". Note
+ * that we treat = and >= as equivalent when scanning forwards (just as we
+ * treat = and <= as equivalent when scanning backwards). We effectively
+ * do the same thing (though with a distinct "a" element/value) each time.

- * _bt_rewind_nonrequired_arrays() -- Rewind SAOP arrays not marked required
- *
- * Called when _bt_advance_array_keys decides to start a new primitive index
- * scan on the basis of the current scan position being before the position
- * that _bt_first is capable of repositioning the scan to by applying an
- * inequality operator required in the opposite-to-scan direction only.
- *
- * Although equality strategy scan keys (for both arrays and non-arrays alike)
- * are either marked required in both directions or in neither direction,
- * there is a sense in which non-required arrays behave like required arrays.
- * With a qual such as "WHERE a IN (100, 200) AND b >= 3 AND c IN (5, 6, 7)",
- * the scan key on "c" is non-required, but nevertheless enables positioning
- * the scan at the first tuple >= "(100, 3, 5)" on the leaf level during the
- * first descent of the tree by _bt_first. Later on, there could also be a
- * second descent, that places the scan right before tuples >= "(200, 3, 5)".
- * _bt_first must never be allowed to build an insertion scan key whose "c"
- * entry is set to a value other than 5, the "c" array's first element/value.
- * (Actually, it's the first in the current scan direction. This example uses
- * a forward scan.)
- *
- * Calling here resets the array scan key elements for the scan's non-required
- * arrays. This is strictly necessary for correctness in a subset of cases
- * involving "required in opposite direction"-triggered primitive index scans.
- * Not all callers are at risk of _bt_first using a non-required array like
- * this, but advancement always resets the arrays when another primitive scan
- * is scheduled, just to keep things simple. Array advancement even makes
- * sure to reset non-required arrays during scans that have no inequalities.
- * (Advancement still won't call here when there are no inequalities, though
- * that's just because it's all handled indirectly instead.)
- *
- * Note: _bt_verify_arrays_bt_first is called by an assertion to enforce that
- * everybody got this right.
- *
- * Note: In practice almost all SAOP arrays are marked required during
- * preprocessing (if necessary by generating skip arrays). It is hardly ever
- * truly necessary to call here, but consistently doing so is simpler.

- * For the libc provider, to provide as much functionality as possible on a
- * variety of platforms without going so far as to implement everything from
- * scratch, we use several implementation strategies depending on the
- * situation:
- *
- * 1. In C/POSIX collations, we use hard-wired code. We can't depend on
- * the <ctype.h> functions since those will obey LC_CTYPE. Note that these
- * collations don't give a fig about multibyte characters.
- *
- * 2. When working in UTF8 encoding, we use the <wctype.h> functions.
- * This assumes that every platform uses Unicode codepoints directly
- * as the wchar_t representation of Unicode. (XXX: ICU makes this assumption
- * even for non-UTF8 encodings, which may be a problem.) On some platforms
- * wchar_t is only 16 bits wide, so we have to punt for codepoints > 0xFFFF.
- *
- * 3. In all other encodings, we use the <ctype.h> functions for pg_wchar
- * values up to 255, and punt for values above that. This is 100% correct
- * only in single-byte encodings such as LATINn. However, non-Unicode
- * multibyte encodings are mostly Far Eastern character sets for which the
- * properties being tested here aren't very relevant for higher code values
- * anyway. The difficulty with using the <wctype.h> functions with
- * non-Unicode multibyte encodings is that we can have no certainty that
- * the platform's wchar_t representation matches what we do in pg_wchar
- * conversions.
- *
- * As a special case, in the "default" collation, (2) and (3) force ASCII
- * letters to follow ASCII upcase/downcase rules, while in a non-default
- * collation we just let the library functions do what they will. The case
- * where this matters is treatment of I/i in Turkish, and the behavior is
- * meant to match the upper()/lower() SQL functions.
- *
- * We store the active collation setting in static variables. In principle
- * it could be passed down to here via the regex library's "struct vars" data
- * structure; but that would require somewhat invasive changes in the regex
- * library, and right now there's no real benefit to be gained from that.
- *
- * NB: the coding here assumes pg_wchar is an unsigned type.

+ * For the libc provider, to provide as much functionality as possible on a
+ * variety of platforms without going so far as to implement everything from
+ * scratch, we use several implementation strategies depending on the
+ * situation:
+ *
+ * 1. In C/POSIX collations, we use hard-wired code. We can't depend on
+ * the <ctype.h> functions since those will obey LC_CTYPE. Note that these
+ * collations don't give a fig about multibyte characters.
+ *
+ * 2. When working in UTF8 encoding, we use the <wctype.h> functions.
+ * This assumes that every platform uses Unicode codepoints directly
+ * as the wchar_t representation of Unicode. (XXX: ICU makes this assumption
+ * even for non-UTF8 encodings, which may be a problem.) On some platforms
+ * wchar_t is only 16 bits wide, so we have to punt for codepoints > 0xFFFF.
+ *
+ * 3. In all other encodings, we use the <ctype.h> functions for pg_wchar
+ * values up to 255, and punt for values above that. This is 100% correct
+ * only in single-byte encodings such as LATINn. However, non-Unicode
+ * multibyte encodings are mostly Far Eastern character sets for which the
+ * properties being tested here aren't very relevant for higher code values
+ * anyway. The difficulty with using the <wctype.h> functions with
+ * non-Unicode multibyte encodings is that we can have no certainty that
+ * the platform's wchar_t representation matches what we do in pg_wchar
+ * conversions.
+ *
+ * As a special case, in the "default" collation, (2) and (3) force ASCII
+ * letters to follow ASCII upcase/downcase rules, while in a non-default
+ * collation we just let the library functions do what they will. The case
+ * where this matters is treatment of I/i in Turkish, and the behavior is
+ * meant to match the upper()/lower() SQL functions.
+ *
+ * We store the active collation setting in static variables. In principle
+ * it could be passed down to here via the regex library's "struct vars" data
+ * structure; but that would require somewhat invasive changes in the regex
+ * library, and right now there's no real benefit to be gained from that.
+ *
+ * NB: the coding here assumes pg_wchar is an unsigned type.
