Please note: When updating your database, you should connect using
psql with the -X flag to prevent any .psqlrc commands from
accidentally triggering the load of a previous DB version.

High-level changes

  • Support for multiple extension versions on different databases in the
    same PostgreSQL instance. This allows different databases to be updated
    independently and provides for smoother updates between versions. No
    more spurious errors in the log as the extension is being
    updated, and new versions no longer require a restart of the database.
  • 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 adjusting the number of partitions for a space dimension
  • Improvements to tablespace handling
