15:34 | New test cases and requirements marks for PRAGMA index_info, index_xinfo, and index_list. (check-in: e5b13634d9 user: drh tags: trunk) | |
14:29 | Revert "PRAGMA index_info" to output only three columns, for complete compatibility with prior versions. The new "PRAGMA index_xinfo" can be used to get the extra information in 4th, 5th, and 6th columns. (check-in: fc543c2c5c user: drh tags: trunk) | |
