21 : * NOTES
22 : * CAPITALS are used to represent terminal symbols.
23 : * non-capitals are used to represent non-terminals.
24 : *
25 : * In general, nothing in this file should initiate database accesses
26 : * nor depend on changeable state (such as SET variables). If you do
27 : * database accesses, your code will fail when we have aborted the
28 : * current transaction and are just parsing commands to find the next
29 : * ROLLBACK or COMMIT. If you make use of SET variables, then you
30 : * will do the wrong thing in multi-query strings like this:
31 : * SET constraint_exclusion TO off; SELECT * FROM foo;
32 : * because the entire string is parsed by gram.y before the SET gets
33 : * executed. Anything that depends on the database or changeable state
34 : * should be handled during parse analysis so that it happens at the
35 : * right time not the wrong time.
36 : *
37 : * WARNINGS
38 : * If you use a list, make sure the datum is a node so that the printing
39 : * routines work.
40 : *
41 : * Sometimes we assign constants to makeStrings. Make sure we don't free
42 : * those.

82 : * The above macro assigns -1 (unknown) as the parse location of any
83 : * nonterminal that was reduced from an empty rule, or whose leftmost
84 : * component was reduced from an empty rule. This is problematic
85 : * for nonterminals defined like
86 : * OptFooList: / * EMPTY * / { ... } | OptFooList Foo { ... } ;
87 : * because we'll set -1 as the location during the first reduction and then
88 : * copy it during each subsequent reduction, leaving us with -1 for the
89 : * location even when the list is not empty. To fix that, do this in the
90 : * action for the nonempty rule(s):
91 : * if (@$ < 0) @$ = @2;
92 : * (Although we have many nonterminals that follow this pattern, we only
93 : * bother with fixing @$ like this when the nonterminal's parse location
94 : * is actually referenced in some rule.)
95 : *
96 : * A cleaner answer would be to make YYLLOC_DEFAULT scan all the Rhs
97 : * locations until it's found one that's not -1. Then we'd get a correct
98 : * location for any nonterminal that isn't entirely empty. But this way
99 : * would add overhead to every rule reduction, and so far there's not been
100 : * a compelling reason to pay that overhead.

107 : * bison >= 2.0. However, in bison 1.875 the default is to use alloca()
108 : * if possible, so there's not really much problem anyhow, at least if

7532 : * An additional restriction is that if the direct-args list ends in a
7533 : * VARIADIC item, the ordered-args list must contain exactly one item that
7534 : * is also VARIADIC with the same type. This allows us to collapse the two
7535 : * VARIADIC items into one, which is necessary to represent the aggregate in
7536 : * pg_proc. We check this at the grammar stage so that we can return a list
7537 : * in which the second VARIADIC item is already discarded, avoiding extra work
7538 : * in cases such as DROP AGGREGATE.
7539 : *
7540 : * The return value of this production is a two-element list, in which the
7541 : * first item is a sublist of FunctionParameter nodes (with any duplicate
7542 : * VARIADIC item already dropped, as per above) and the second is an integer
7543 : * Value node, containing -1 if there was no ORDER BY and otherwise the number
7544 : * of argument declarations before the ORDER BY. (If this number is equal
7545 : * to the first sublist's length, then we dropped a duplicate VARIADIC item.)
7546 : * This representation is passed as-is to CREATE AGGREGATE; for operations
7547 : * on existing aggregates, we can just apply extractArgTypes to the first
7548 : * sublist.

10766 : * The rule returns either a single SelectStmt node or a tree of them,
10767 : * representing a set-operation tree.
10768 : *
10769 : * There is an ambiguity when a sub-SELECT is within an a_expr and there
10770 : * are excess parentheses: do the parentheses belong to the sub-SELECT or
10771 : * to the surrounding a_expr? We don't really care, but bison wants to know.
10772 : * To resolve the ambiguity, we are careful to define the grammar so that
10773 : * the decision is staved off as long as possible: as long as we can keep
10774 : * absorbing parentheses into the sub-SELECT, we will do so, and only when
10775 : * it's no longer possible to do that will we decide that parens belong to
10776 : * the expression. For example, in "SELECT (((SELECT 2)) + 3)" the extra
10777 : * parentheses are treated as part of the sub-select. The necessity of doing
10778 : * it that way is shown by "SELECT (((SELECT 2)) UNION SELECT 2)". Had we
10779 : * parsed "((SELECT 2))" as an a_expr, it'd be too late to go back to the
10780 : * SELECT viewpoint when we see the UNION.
10781 : *
10782 : * This approach is implemented by defining a nonterminal select_with_parens,
10783 : * which represents a SELECT with at least one outer layer of parentheses,
10784 : * and being careful to use select_with_parens, never '(' SelectStmt ')',
10785 : * in the expression grammar. We will then have shift-reduce conflicts
10786 : * which we can resolve in favor of always treating '(' <select> ')' as
10787 : * a select_with_parens. To resolve the conflicts, the productions that
10788 : * conflict with the select_with_parens productions are manually given
10789 : * precedences lower than the precedence of ')', thereby ensuring that we
10790 : * shift ')' (and then reduce to select_with_parens) rather than trying to
10791 : * reduce the inner <select> nonterminal to something else. We use UMINUS
10792 : * precedence for this, which is a fairly arbitrary choice.
10793 : *
10794 : * To be able to define select_with_parens itself without ambiguity, we need
10795 : * a nonterminal select_no_parens that represents a SELECT structure with no
10796 : * outermost parentheses. This is a little bit tedious, but it works.
10797 : *
10798 : * In non-expression contexts, we use SelectStmt which can represent a SELECT
10799 : * with or without outer parentheses.

12505 : * General expressions
12506 : * This is the heart of the expression syntax.
12507 : *
12508 : * We have two expression types: a_expr is the unrestricted kind, and
12509 : * b_expr is a subset that must be used in some places to avoid shift/reduce
12510 : * conflicts. For example, we can't do BETWEEN as "BETWEEN a_expr AND a_expr"
12511 : * because that use of AND conflicts with AND as a boolean operator. So,
12512 : * b_expr is used in BETWEEN and we remove boolean keywords from b_expr.
12513 : *
12514 : * Note that '(' a_expr ')' is a b_expr, so an unrestricted expression can
12515 : * always be used by surrounding it with parens.
12516 : *
12517 : * c_expr is all the productions that are common to a_expr and b_expr;
12518 : * it's factored out just to eliminate redundant coding.
12519 : *
12520 : * Be careful of productions involving more than one terminal token.
12521 : * By default, bison will assign such productions the precedence of their
12522 : * last terminal, but in nearly all cases you want it to be the precedence
12523 : * of the first terminal instead; otherwise you will not get the behavior
12524 : * you expect! So we use %prec annotations freely to set precedences.
