-=head1 BUGS
-
-Problem with SQL::Translator::Producer::Oracle: it is keeping track
-of the last sequence number used, so as not to duplicate them, which
-is reasonable. However on runs past the first, it seems to be
-creating multiple constraint lines, that look like:
-
- CONSTRAINT i_sessions_pk_2 PRIMARY KEY (id),
- CONSTRAINT i_sessions_pk_3 PRIMARY KEY (id)
-
-This is a very preliminary finding, and needs to be investigated more
-thoroughly, of course.
