Alan Guo Xiang Tan 5ddae1c574 DEV: Rerun AddIndexToPostStatComposerColumns migration (#31765)
The previous version of the migration is not idempotent and can result
in indexes created but marked as "invalid" by Postgres.

Per postgres documentation:

If a problem arises while scanning the table, such as a deadlock or a
uniqueness violation in a unique index,
the CREATE INDEX command will fail but leave behind an "invalid" index.
This index will be ignored for querying
purposes because it might be incomplete; however it will still consume
update overhead. The recommended recovery
  method in such cases is to drop the index and try again to perform
  CREATE INDEX CONCURRENTLY.
