The old code assumes that post-aggregator prefixes are one character
long followed by numbers. This isn't always true (we may pad with
underscores to avoid conflicts). Instead, the new code uses a different
base prefix for sort-project postaggregators ("s" instead of "p") and
uses the usual Calcites.findUnusedPrefix function to avoid conflicts.

This fixes a bug introduced in #5788, which is new in 0.12.3, so I think we should include this fix too. |
