100 * State information used during parse analysis
101 *
102 * parentParseState: NULL in a top-level ParseState. When parsing a subquery,
103 * links to current parse state of outer query.
104 *
105 * p_sourcetext: source string that generated the raw parsetree being
106 * analyzed, or NULL if not available. (The string is used only to
107 * generate cursor positions in error messages: we need it to convert
108 * byte-wise locations in parse structures to character-wise cursor
109 * positions.)
110 *
111 * p_rtable: list of RTEs that will become the rangetable of the query.
112 * Note that neither relname nor refname of these entries are necessarily
113 * unique; searching the rtable by name is a bad idea.
114 *
115 * p_rteperminfos: list of RTEPermissionInfo containing an entry corresponding
116 * to each RTE_RELATION entry in p_rtable.
117 *
118 * p_joinexprs: list of JoinExpr nodes associated with p_rtable entries.
119 * This is one-for-one with p_rtable, but contains NULLs for non-join
120 * RTEs, and may be shorter than p_rtable if the last RTE(s) aren't joins.
121 *
122 * p_nullingrels: list of Bitmapsets associated with p_rtable entries, each
123 * containing the set of outer-join RTE indexes that can null that relation
124 * at the current point in the parse tree. This is one-for-one with p_rtable,
125 * but may be shorter than p_rtable, in which case the missing entries are
126 * implicitly empty (NULL). That rule allows us to save work when the query
127 * contains no outer joins.
128 *
129 * p_joinlist: list of join items (RangeTblRef and JoinExpr nodes) that
130 * will become the fromlist of the query's top-level FromExpr node.
131 *
132 * p_namespace: list of ParseNamespaceItems that represents the current
133 * namespace for table and column lookup. (The RTEs listed here may be just
134 * a subset of the whole rtable. See ParseNamespaceItem comments below.)
135 *
136 * p_lateral_active: true if we are currently parsing a LATERAL subexpression
137 * of this parse level. This makes p_lateral_only namespace items visible,
138 * whereas they are not visible when p_lateral_active is FALSE.
139 *
140 * p_ctenamespace: list of CommonTableExprs (WITH items) that are visible
141 * at the moment. This is entirely different from p_namespace because a CTE
142 * is not an RTE, rather "visibility" means you could make an RTE from it.
143 *
144 * p_future_ctes: list of CommonTableExprs (WITH items) that are not yet
145 * visible due to scope rules. This is used to help improve error messages.
146 *
147 * p_parent_cte: CommonTableExpr that immediately contains the current query,
148 * if any.
149 *
150 * p_target_relation: target relation, if query is INSERT/UPDATE/DELETE/MERGE
151 *
152 * p_target_nsitem: target relation's ParseNamespaceItem.
153 *
154 * p_grouping_nsitem: the ParseNamespaceItem that represents the grouping step.
155 *
156 * p_is_insert: true to process assignment expressions like INSERT, false
157 * to process them like UPDATE. (Note this can change intra-statement, for
158 * cases like INSERT ON CONFLICT UPDATE.)
159 *
160 * p_windowdefs: list of WindowDefs representing WINDOW and OVER clauses.
161 * We collect these while transforming expressions and then transform them
162 * afterwards (so that any resjunk tlist items needed for the sort/group
163 * clauses end up at the end of the query tlist). A WindowDef's location in
164 * this list, counting from 1, is the winref number to use to reference it.
165 *
166 * p_expr_kind: kind of expression we're currently parsing, as per enum above;
167 * EXPR_KIND_NONE when not in an expression.
168 *
169 * p_next_resno: next TargetEntry.resno to assign, starting from 1.
170 *
171 * p_multiassign_exprs: partially-processed MultiAssignRef source expressions.
172 *
173 * p_locking_clause: query's FOR UPDATE/FOR SHARE clause, if any.
174 *
175 * p_locked_from_parent: true if parent query level applies FOR UPDATE/SHARE
176 * to this subquery as a whole.
177 *
178 * p_resolve_unknowns: resolve unknown-type SELECT output columns as type TEXT
179 * (this is true by default).
180 *
181 * p_hasAggs, p_hasWindowFuncs, etc: true if we've found any of the indicated
182 * constructs in the query.
183 *
184 * p_last_srf: the set-returning FuncExpr or OpExpr most recently found in
185 * the query, or NULL if none.
186 *
187 * p_pre_columnref_hook, etc: optional parser hook functions for modifying the
188 * interpretation of ColumnRefs and ParamRefs.
189 *
190 * p_ref_hook_state: passthrough state for the parser hook functions.

248 * p_names contains the table name and column names exposed by this nsitem.
249 * (Typically it's equal to p_rte->eref, but for a JOIN USING alias it's
250 * equal to p_rte->join_using_alias. Since the USING columns will be the
251 * join's first N columns, the net effect is just that we expose only those
252 * join columns via this nsitem.)
253 *
254 * p_rte and p_rtindex link to the underlying rangetable entry, and
255 * p_perminfo to the entry in rteperminfos.
256 *
257 * The p_nscolumns array contains info showing how to construct Vars
258 * referencing the names appearing in the p_names->colnames list.
259 *
260 * Namespace items with p_rel_visible set define which RTEs are accessible by
261 * qualified names, while those with p_cols_visible set define which RTEs are
262 * accessible by unqualified names. These sets are different because a JOIN
263 * without an alias does not hide the contained tables (so they must be
264 * visible for qualified references) but it does hide their columns
265 * (unqualified references to the columns refer to the JOIN, not the member
266 * tables, so we must not complain that such a reference is ambiguous).
267 * Conversely, a subquery without an alias does not hide the columns selected
268 * by the subquery, but it does hide the auto-generated relation name (so the
269 * subquery columns are visible for unqualified references only). Various
270 * special RTEs such as NEW/OLD for rules may also appear with only one flag
271 * set.
272 *
273 * While processing the FROM clause, namespace items may appear with
274 * p_lateral_only set, meaning they are visible only to LATERAL
275 * subexpressions. (The pstate's p_lateral_active flag tells whether we are
276 * inside such a subexpression at the moment.) If p_lateral_ok is not set,
277 * it's an error to actually use such a namespace item. One might think it
278 * would be better to just exclude such items from visibility, but the wording
279 * of SQL:2008 requires us to do it this way. We also use p_lateral_ok to
280 * forbid LATERAL references to an UPDATE/DELETE target table.
281 *
282 * While processing the RETURNING clause, special namespace items are added to
283 * refer to the OLD and NEW state of the result relation. These namespace
284 * items have p_returning_type set appropriately, for use when creating Vars.
285 * For convenience, this information is duplicated on each namespace column.
286 *
287 * At no time should a namespace list contain two entries that conflict
288 * according to the rules in checkNameSpaceConflicts; but note that those
289 * are more complicated than "must have different alias names", so in practice
290 * code searching a namespace list has to check for ambiguous references.
