I think what you are saying a feature is really a bug. I am fairly sure
that when someone says to_tsquery('english', 's:*') one is looking for
an entry that has a *non-stopword* word that starts with 's'. And
specially so in a text search configuration that eliminates stop words.
Does it even make sense to stem, abbreviate, synonym for a few letters?
It will be so unpredictable.
