Changelog entry (a user-readable short description of the changes that goes to CHANGELOG.md):

Allow export partition through different partition expressions as long as the destination expression does not repartition the data. This is validated at schedule time through two mechanisms:

  1. Structural match: in case the source and destination are identical, the destination expression is a subset of the source expression or the destination expression can be entirely computed using only constants and the exact values guaranteed (pinned) by the source.
  2. Dynamic proof: the destination expression is monotonic over the source partition min/max range.
