   I agree with @seddonm1  that ideally we would follow Postgres when possible so we can just re-use all their documentation and semantics and so we don't end up inadvertently creating yet another SQL dialect like spark. 
   
   Specifically in this case, it looks like the relevant postgres function is called `TRIM`. A screen shot from https://www.postgresql.org/docs/9.1/functions-string.html
