History:
When a log file switch occured in the middle of a sequence flush (sequences are only
flushed every 32 values by default), the sequence was lost. Fixed.
When a log file switch occured just after a truncate table or drop table statement,
the database could not be started normally (RECOVER=1 was required). Fixed.
There was a bug in the recovery code that would stop recovery sometimes when
there are multiple log files to recover.

The recovery tool didn't work correctly for tables without rows.
For years below 1, the YEAR method didn't return the correct value,
