Hi @intermittentnrg, is there anything you need to move this from Draft to Ready for Review?
I would like to have this merged as well.

Awesome. It's good as is, but should be expanded to cover all methods in migration_helpers.

@rapito would you like to push it forward? as you can also be a beta-tester 🤓

Sounds good, I can find some time to finish this up.

the methods we need to support are:

• create_table if options.key?(:hypertable)
• create_continuous_aggregate
• create_continuous_aggregates (alias_method)
• drop_continuous_aggregate
• drop_continuous_aggregates (alias_method)
• create_continuous_aggregate_policy
• remove_continuous_aggregate_policy (alias_method)
• create_retention_policy
• add_retention_policy (alias_method)
• remove_retention_policy
• add_compression_policy

drop_* can just be irreversible, tho rails does support extra options that are used only when reversing

So short list without drop_* methods and removing duplicates from aliases.

• create_continuous_aggregate
• create_continuous_aggregate_policy
• create_retention_policy
• add_compression_policy
