Обсуждение: pgsql: Fix error reporting for SQL/JSON path type mismatches
Fix error reporting for SQL/JSON path type mismatches transformJsonFuncExpr() used exprType()/exprLocation() on the possibly coerced path expression, which could be NULL when coercion to jsonpath failed, leading to "cache lookup failed for type 0" errors. Preserve the original expression node so that type and location in the "must be of type jsonpath" error are reported correctly. Add regression tests to cover these cases.
