Oh, I accidentally renamed one of the old functions, my mistake.

Just to keep some level of uniformity in function names. But also i’m
not insisting.

There is already several functions named ts_* (ts_rank, ts_headline, ts_rewrite)
and two named starting from tsvector_* (tsvector_update_trigger, tsvector_update_trigger_column).
Personally I’d prefer ts_ over tsvector_ since it is shorter, and still keeps semantics.
