Timescale 2.7 released a new version of Continuous Aggregate (#4269) that store the final aggregation state instead of the byte array of the partial aggregate state, offering multiple opportunities of optimizations as well a more compact form. When upgrading to Timescale 2.7, new created Continuous Aggregates are using the new format, but existing Continuous Aggregates keep using the format they were defined with. Created a procedure to upgrade existing Continuous Aggregates from the old format to the new format, by calling a simple procedure: test=# CALL cagg_migrate('conditions_summary_daily'); Closes #4424
