Assertion `page_st != 2' failed in read_big_block or server hangs upon concurrent SELECT from partitioned S3 table

    Details

      Description

      Note: The test case currently fails every time for me on 10.5 debug builds, but it's a race condition, so run repeatedly if it doesn't fail right away. Remember to use all necessary S3 options and clean the bucket between the tries.

      The failure comes in two forms, either as an assertion failure, or as server hang.
