Charis d34cc65e30 fix(studio): handle large cron.job_run_details table gracefully (#41992)
* fix(studio): check job_run_details size in cron display

When cron.job_run_details grows too large (200k+ rows), loading the
cron jobs overview can timeout and affect other queries by pulling
excessive data into shared buffers.

This change:
- Estimates table size using pg_stat before fetching cron jobs data
- Shows a cleanup notice when the table exceeds the threshold
- Provides batched deletion using ctid ranges to avoid buffer pollution
- Allows scheduling an automated daily cleanup cron job
- Handles timeout errors gracefully with a "suspected overflow" state

The useCronJobsData hook now returns a discriminated union status that
tracks loading, estimate-error, overflow-confirmed, overflow-suspected,
and ready states, allowing the UI to respond appropriately to each case.

* fix(studio): use index when querying cron.job_run_details

cron.job_run_details is only indexed by runid, not by start_time. Change
the query to use the runid index (which gives the same result, since
runid is auto-incrementing).

Writing pages

Rough guidelines

  • Try to break down your pages into smaller building blocks - components which are tightly coupled to a page can be placed within the folder components/interfaces/xxx/... (Refer to the README.md under the components folder)
  • Keep to using useState hooks for any UI related logic, do not create MobX local stores to handle UI logic.

Template for building pages

import { NextPage } from 'next'
import { withAuth } from 'hooks/misc/withAuth'

// Import the corresponding layout based on the page
import { Layout } from 'components/layouts'

// Import the main building blocks of the page
import { ... } from 'components/interfaces/xxx'

// Import reusable UI components if needed
import { ... } from 'components/ui/xxx'

// Name your page accordingly
const Page: NextPage = () => {

  return (
    <Layout>
      <div>Page content</div>
    </Layout>
  )
}

export default withAuth(Page)
