commit 500347b69f2bc95c3420235466670b20694f5a50 Author: Tom Lane <[email protected]> AuthorDate: Mon Aug 10 06:38:23 2026 -0700 Replace fixed-size, too-short array with a palloc'd one. MatchNamedCall's arggiven array was declared FUNC_MAX_ARGS long, but we may actually use up to pronallargs elements, and that can be more than FUNC_MAX_ARGS if the function has OUT arguments (cf. ProcedureCreate). Convert it to a palloc'd array.
