Thread: pgsql: Catch invalid typlens in a couple of places

Catch invalid typlens in a couple of places

Rearrange the logic in record_image_cmp() and record_image_eq() to
error out on unexpected typlens (either not supported there or
completely invalid due to corruption).  Barring corruption, this is
not possible today but it seems more future-proof and robust to fix
this.
