Summary

  • document grouped and analytic LISTAGG forms
  • explain ordering, null handling, delimiters, and the 4,000-byte result limit
  • include grouped, analytic, and FILTER examples
  • identify unsupported DISTINCT, inline ORDER BY, and ON OVERFLOW syntax

Fixes #1433

Verification

  • make -C doc/src/sgml check
  • make -C doc/src/sgml html
  • git diff --check

The SGML and HTML checks were run in an out-of-tree cumulative documentation build containing this change and the other independently proposed documentation additions.

Warning

Review limit reached

@Z95-cmyk, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 59 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
