/* Opcode: OpenPseudo P1 P2 P3 * *
**
** Open a new cursor that points to a fake table that contains a single
** row of data. The content of that one row in the content of memory
** register P2 when P5==0. In other words, cursor P1 becomes an alias for the
** MEM_Blob content contained in register P2. When P5==1, then the
** row is represented by P3 consecutive registers beginning with P2.
