The problem with foreign keys (and triggers !) as separate rows of SQLITE_MASTER is that it would all have to be one long string, so you'd have to write a parser. I think a better idea would be to expand table_info with a second parameter so it could list all tables, and report on columns, indexes, triggers and foreign keys all in one PRAGMA. Then all the other PRAGMAs that do this could be removed.
