数据自动按时间和空间分片(chunk)
该版本值得关注的变更

  • Streamlined update process for smaller binary/package sizes
  • Significant refactoring to simplify and improve codebase, including
    improvements to error handling, security/permissions, and more
  • Corrections to edge-case scenarios involving dropping schemas,
    hypertables, dimensions, and more
  • Correctness improvements through propagating reloptions from main
    table to chunk tables and blocking ONLY commands that try to alter
    hypertables (i.e., changes should be applied to chunks as well)
  • Addition of a migrate_data option to create_hypertable to allow
    non-empty tables to be turned into hypertables without separate
    creation & insertion steps. Note, this option may take a while if the
    original table has lots of data
  • Support for ALTER TABLE RENAME CONSTRAINT
  • Support for adjusting the number of partitions for a space dimension
  • Improvements to tablespace handling
