…olumns Row/SimpleQueryRow validated the requested index against the RowDescription column count but indexed the ranges vector built from the DataRow field count, which the server controls independently. A DataRow with fewer fields than advertised columns made get/try_get (and a plain 0..row.len() loop) panic with an out-of-bounds index. Validate the two counts match when the row is built so the mismatch surfaces as a recoverable error instead.

DataRowwith fewer fields than its row description declares now produces an error when the row is built, instead of a panic when a missing column is read. This fixes RUSTSEC-2026-0178 (GHSA-3gjw-f78c-vvpw) for this fork.The upstream tests construct
