|15:16||When loading a database schema that contains an index definition that includes a COLLATE clause for which the collation sequence is unavailable, do not assume that that index uses BINARY instead. Fix for [0fc59f908b]. (check-in: 6dae62c4 user: dan tags: trunk)|

If a database schema uses an application-defined collating sequence, and an instance of SQLite is run on that database that does not have the necessary collating sequence defined, then the "REINDEX" and "PRAGMA integrity_check" commands run without generating an error and substitute the built-in BINARY collating sequence in place of the application-defined collating sequence. Running the REINDEX command this way corrupts the index (though the corruption can be reversed by rerunning REINDEX in a new database connection where the application-defined collating sequence has been defined). Running PRAGMA integrity_check this way results in spurious errors.
This problem appears to have been introduced by check-in [8542e6180d4321d] and first appeared in release 3.7.15.
