Hello.
There is patch that adds some editing routines for tsvector type.
tsvector delete(tsvector, text)
removes entry from tsvector by lexeme name
set unnest(tsvector)
expands a tsvector to a set of rows. Each row has following columns: lexeme, postings, weights.
text[] to_array(tsvector)
converts tsvector to array of lexemes
tsvector to_tsvector(text[])
converts array of lexemes to tsvector
