If a final sequence file or directory name matches a pattern
which is recognised to indicate a ‘pending acceptance’ status,
the final data (if any exists) for that sequence will be deleted
and a comment added to the effect that the sequence has been
marked as ‘pending’.
To accept the sequence, rename its final file or directory name
accordingly.
Note: it is the *final* data that is searched for a matching
pattern, not the raw.
Closes#91.
When the database is recreated, the sequences
used in the events_timed and events_seq tables
will be at their initial values, which will
almost certainly conflict with existing data
when it is imported via COPY.
With this commit, we set the current value for
those sequences to something usable.
Fixes#33.
