I see your point. I will rework a patch to keep the backward
compatibility and return the TSL_FILTER entry into documentation.

I changed the name bacause it may contain more than one dictionary
interconnected via operators (e.g. 'english_stem UNION simple') and
the word 'dictionary' doesn't fully describe a content of the column
now. Also, a type of column was changed from regdictionary to text in
order to put operators into the output.
