Обсуждение: pgsql: Fix get_expr_result_type() to find field names for RECORD Consts
Fix get_expr_result_type() to find field names for RECORD Consts. This is a back-patch of commit d57534740 ("Fix EXPLAIN of SEARCH BREADTH FIRST with a constant initial value") into pre-v14 branches. At the time I'd thought it was not needed in branches that lack the SEARCH/CYCLE feature, but that was just a failure of imagination. It's possible to demonstrate "record type has not been registered" failures in older branches too, during deparsing of views that contain references to fields of composite constants. Back-patch only the code changes, as the test cases added by d57534740 all require SEARCH/CYCLE syntax. A suitable test case will be added in the upcoming fix for bug #18077.
