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

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
