[mikehgrantsgov]

Summary

Fixes #3851

Time to review: 15 mins

Changes proposed

Add SQL transaction script to remove historical data from our environments.
Update seed script to generate historical data to test deletion (this can be removed in a follow up ticket).

Context for reviewers

Additional context in ticket, but remove versioned records from the following tables:
opportunity_summary
link_opportunity_summary_funding_instrument
link_opportunity_summary_funding_category
link_opportunity_summary_applicant_type

Tested working in a local environment.

Additional information

Leaving this in draft status for additional review.

I would make the ROLLBACK uncommented and the COMMIT require the extra effort, just in case the script gets run end-to-end by accident.

Makes sense!

I think the SQL looks good - I don't think we need to check in these changes (also avoids needing to undo the seed script). The SQL / script won't even function once we remove the revision number column in the next ticket after we run all of this.

Makes sense. Let me know when you want to pair on running these and we can close the PR / leave it unmerged.

@mikehgrantsgov - apologies on missing your message earlier - happy to pair on this.

One caveat to your script from some recent stuff I've run - our current way of running adhoc queries against the db via the RDS query editor doesn't actually let you run transactions. The editor itself either auto-commits every command, or at the end of every command. There's no option to control the start/end of the transaction yourself.

Closing PR as we will not merge and DELETEs have been done in all envs
