    Description

      The results of the blobAs*() functions are not validated.

      Here are some examples:

      Non-type1 UUID inserted into timeuuid column:

      create table foo (k int primary key, v timeuuid);
      insert into foo (0, blobAsTimeuuid(0x00000000000000000000000000000000));
      

      Blob with length > 4 inserted into an int column:

      create table bar (k int primary key, v int);
      insert into bar (k, v) VALUES (0, blobAsInt(0x0000000000));
      

      Non-ascii characters inserted into an ascii column:

      create table baz (k int primary key, v ascii);
      insert into baz (k, v) VALUES (0, blobAsAscii(0xFFFFFFFF));
      

      Some of these (like the int column) could cause issues that look like corruption.
