* State information used during parse analysis
*
* parentParseState: NULL in a top-level ParseState. When parsing a subquery,
* links to current parse state of outer query.
*
* p_sourcetext: source string that generated the raw parsetree being
* analyzed, or NULL if not available. (The string is used only to
* generate cursor positions in error messages: we need it to convert
* byte-wise locations in parse structures to character-wise cursor
* positions.)
*
* p_rtable: list of RTEs that will become the rangetable of the query.
* Note that neither relname nor refname of these entries are necessarily
* unique; searching the rtable by name is a bad idea.
*
* p_joinexprs: list of JoinExpr nodes associated with p_rtable entries.
* This is one-for-one with p_rtable, but contains NULLs for non-join
* RTEs, and may be shorter than p_rtable if the last RTE(s) aren't joins.
*
* p_joinlist: list of join items (RangeTblRef and JoinExpr nodes) that
* will become the fromlist of the query's top-level FromExpr node.
*
* p_namespace: list of ParseNamespaceItems that represents the current
* namespace for table and column lookup. (The RTEs listed here may be just
* a subset of the whole rtable. See ParseNamespaceItem comments below.)
*
* p_lateral_active: true if we are currently parsing a LATERAL subexpression
* of this parse level. This makes p_lateral_only namespace items visible,
* whereas they are not visible when p_lateral_active is FALSE.
*
* p_ctenamespace: list of CommonTableExprs (WITH items) that are visible
* at the moment. This is entirely different from p_namespace because a CTE
* is not an RTE, rather "visibility" means you could make an RTE from it.
*
* p_future_ctes: list of CommonTableExprs (WITH items) that are not yet
* visible due to scope rules. This is used to help improve error messages.
*
* p_parent_cte: CommonTableExpr that immediately contains the current query,
* if any.
*
* p_target_relation: target relation, if query is INSERT, UPDATE, or DELETE.
*
* p_target_nsitem: target relation's ParseNamespaceItem.
*
* p_is_insert: true to process assignment expressions like INSERT, false
* to process them like UPDATE. (Note this can change intra-statement, for
* cases like INSERT ON CONFLICT UPDATE.)
*
* p_windowdefs: list of WindowDefs representing WINDOW and OVER clauses.
* We collect these while transforming expressions and then transform them
* afterwards (so that any resjunk tlist items needed for the sort/group
* clauses end up at the end of the query tlist). A WindowDef's location in
* this list, counting from 1, is the winref number to use to reference it.
*
* p_expr_kind: kind of expression we're currently parsing, as per enum above;
* EXPR_KIND_NONE when not in an expression.
*
* p_next_resno: next TargetEntry.resno to assign, starting from 1.
*
* p_multiassign_exprs: partially-processed MultiAssignRef source expressions.
*
* p_locking_clause: query's FOR UPDATE/FOR SHARE clause, if any.
*
* p_locked_from_parent: true if parent query level applies FOR UPDATE/SHARE
* to this subquery as a whole.
*
* p_resolve_unknowns: resolve unknown-type SELECT output columns as type TEXT
* (this is true by default).
*
* p_hasAggs, p_hasWindowFuncs, etc: true if we've found any of the indicated
* constructs in the query.
*
* p_last_srf: the set-returning FuncExpr or OpExpr most recently found in
* the query, or NULL if none.
*
* p_pre_columnref_hook, etc: optional parser hook functions for modifying the
* interpretation of ColumnRefs and ParamRefs.
*
* p_ref_hook_state: passthrough state for the parser hook functions.

*
* Namespace items with p_rel_visible set define which RTEs are accessible by
* qualified names, while those with p_cols_visible set define which RTEs are
* accessible by unqualified names. These sets are different because a JOIN
* without an alias does not hide the contained tables (so they must be
* visible for qualified references) but it does hide their columns
* (unqualified references to the columns refer to the JOIN, not the member
* tables, so we must not complain that such a reference is ambiguous).
* Various special RTEs such as NEW/OLD for rules may also appear with only
* one flag set.
*
* While processing the FROM clause, namespace items may appear with
* p_lateral_only set, meaning they are visible only to LATERAL
* subexpressions. (The pstate's p_lateral_active flag tells whether we are
* inside such a subexpression at the moment.) If p_lateral_ok is not set,
* it's an error to actually use such a namespace item. One might think it
* would be better to just exclude such items from visibility, but the wording
* of SQL:2008 requires us to do it this way. We also use p_lateral_ok to
* forbid LATERAL references to an UPDATE/DELETE target table.
*
* At no time should a namespace list contain two entries that conflict
* according to the rules in checkNameSpaceConflicts; but note that those
* are more complicated than "must have different alias names", so in practice
* code searching a namespace list has to check for ambiguous references.
