Postgresql tsvector datatype not recognized in schema.rb
Postgresql now supports full-text search via the tsvector datatype. However, tsvector is not currently known to the the PostgresqlAdapter. As such, when migrations are run schema.rb replaces table definitions with an undefined datatype error.
Attached is a patch which gives ActiveRecord knowledge of tsvector. With this patch, tsvector attributes can be added via migrations while also keeping the table definition intact in schema.rb.

Robert SosinskiAttaching updated patch. PostgreSQLColumn#simplified_type should probably specify tsvector as a :tsvector, not a :string.

Some more info about this. So, ActiveRecord seems to cast tsvector to a String when read from a record. ALso, if migrations define tsvectors as type tsvector in schema.rb, rails errors out during rake db:test:prepare. Interested if the migration should then just define a tevector as a String in schema.rb then?
Interested in hearing any ideas.
Thanks.

Scott Lowe- Assigned user set to Aaron Patterson
I've written some simple tests to support the PostgreSQL tsvector data type patch for #6073 Postgresql tsvector datatype not recognized in schema.rb.
Writing these tests has raised some questions. Whilst we can now schema dump without fear, is the data type useful on it's own? I can't think of a case where I would use the tsvector type without a trigger and of course that is not something that is presently supported in the schema DSL (or perhaps I've missed something?).
I've attached a patch which includes Robert Sosinski's patch and my tests.
