contrib/adddepend failed 8.1.2

Hi.

I was trying to upgrade PostgreSQL from 7.2.8 to 8.1.2.
Dump and restore work well. But adddepend was failed.

To fix it, this regexp
$seq =~ s|^nextval\(["']+([^'"\)]+)["']+.*\)$|$1|g;
need to change
$seq =~ s|^nextval\(\(["']+([^'"\)]+)["']+.*\)$|$1|g;
or
$seq =~ s|^nextval\(\(?["']+([^'"\)]+)["']+.*\)$|$1|g;

[ishida@localhost adddepend]$ ./adddepend -Y -d ishida

Upgrade the Unique Constraint style via:

DROP INDEX t_i_key RESTRICT;
ALTER TABLE t ADD CONSTRAINT t_i_key UNIQUE (i);

NOTICE: ALTER TABLE / ADD UNIQUE will create implicit index "t_i_key"
for table "t"
Do you wish to upgrade Sequence 'nextval(('"t_i_seq"'::text)::regclass)'
to SERIAL?
Found on column t.i
