When you try storing a tsquery in a column does it alert you if you have an
invalid syntax at that point? Storing it as text would mean not finding out
until you try to use the query.

Is converting a text query into the internal format faster or less memory
intensive than converting text into the internal representation? When you run
a query like "WHERE '...' @@ col" if there wasn't a tsquery data type then
'...' would have to be parsed over and over again for each row.
