Re: [sqlite] rowid versus docid for fts3.

Unfortunately, the reason fts2 couldn't be "fixed" was because you can't perform the necessary ALTER TABLE if the column you're adding is a primary key. Since the only alternative would be to build a new table and copy everything over, it seemed more reasonable to just let the app developer do

RE: [sqlite] (select *) VS (select column1, column2 ...)

In general, it's best to only include the columns you need in the SELECT clause. And not just with SQLite - that's the best approach when dealing with any database. SQLite is a bit more forgiving because there's no network between the client and the database to slow things down, but that's
