When ALTER TABLE ... ALTER COLUMN TYPE (or any subcommand that rebuilds them) drops and re-creates the extended statistics objects depending on the altered column, the re-created objects were owned by the role running ALTER TABLE rather than by the original owner of the statistics. Remember each object's owner before dropping it, and restore it on re-creation. CreateStatistics()'s signature changes and CreateStatsStmt gains a field, but no known third-party code calls the former or constructs the latter.
