| 16:48 | Update the sqldiff utility so that if the --vtab switch is specified "rtree", "fts3", "fts4" and "fts5" tables are diff'd directly and the underlying real database tables ignored. Without this switch, all virtual tables are ignored and the diff is performed on the underlying real tables. (check-in: b8671e9434 user: dan tags: trunk) | |
