Damien Neil c23579f031 database/sql: avoid clobbering driver-owned memory in RawBytes ... Depending on the query, a RawBytes can contain memory owned by the driver or by database/sql: If the driver provides the column as a []byte, RawBytes aliases that []byte. If the driver provides the column as any other type, RawBytes contains memory allocated by database/sql. Prior to this CL, Rows.Scan will reuse existing capacity in a RawBytes to permit a single allocation to be reused across rows. When a RawBytes is reused across queries, this can result in database/sql writing to driver-owned memory. Add a buffer to Rows to store RawBytes data, and reuse this buffer across calls to Rows.Scan.
