* 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_relnamespace: list of RTEs that represents the current namespace for
* table lookup, ie, those RTEs that are accessible by qualified names.
* This may be just a subset of the rtable + joinlist, and/or may contain
* entries that are not yet added to the main joinlist.
*
* p_varnamespace: list of RTEs that represents the current namespace for
* column lookup, ie, those RTEs that are accessible by unqualified names.
* This is different from p_relnamespace because a JOIN without an alias does
* not hide the contained tables (so they must still be in p_relnamespace)
* but it does hide their columns (unqualified references to the columns must
* refer to the JOIN, not the member tables). Other special RTEs such as
* NEW/OLD for rules may also appear in just one of these lists.
*
* p_ctenamespace: list of CommonTableExprs (WITH items) that are visible
* at the moment. This is different from p_relnamespace because you have
* to make an RTE before you can access a CTE.
*
* 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_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.
