# Important: Job lists break starttime ties by uid {#important-job-lists-break-starttime-ties-by-uid}

## Description {#description}

The job lists order by `starttime` through the repository's
`$defaultOrderings`. `starttime` is `0` for every job that was
never scheduled, so most of a typical list tied, and the relative order of the
tied records belonged to the database. On PostgreSQL that is not the same list
twice. The default orderings now carry `uid` ascending as a tiebreaker.

## Impact {#impact}

No visible change is expected on SQLite, MySQL and MariaDB: within equal
`starttime` values, `uid` ascending is the order they return in
practice, and it is guaranteed now rather than coincidental. PostgreSQL promises
no order without one, so an installation on it may see such a list change once.
Jobs with different `starttime` values keep their order.

## Affected Installations {#affected-installations}

Every installation rendering the **Jobs List** plugin, observably those
on PostgreSQL.
