FromField instance for TSVector

[delanoe]

Hello, TSVector type of Postgres is the following: https://www.postgresql.org/docs/8.3/datatype-textsearch.html Example of tsvector: "'cat':2 'dog:5 'animal':10"

To add the FromField instance we need a parser. Do you have an example of implementation that could help to parser for the TSVector FromField instances ?

Specifications would be the following: type TSVector = [Vector] data Vector = Vector { text :: Text , position :: Int }

Many thanks for your help
