hi,
Hope you might have came accross this problem earlier. it exists in
7.1.x and 7.2 as well.
while creating a table with a column of type 'serial', well a sequence
has been created and the default value of that field is set to nextval
of that sequence, fine. But while dropping that table, why aren't that
sequence dropped?
example:
bhuvandb=# CREATE TABLE seq_test (id serial, name text);
NOTICE: CREATE TABLE will create implicit sequence 'seq_test_id_seq'
for SERIAL column 'seq_test.id'
NOTICE: CREATE TABLE/UNIQUE will create implicit index
'seq_test_id_key' for table 'seq_test'
CREATE
bhuvandb=# DROP TABLE seq_test ;
DROP
bhuvandb=# CREATE TABLE seq_test (id serial, name text);
NOTICE: CREATE TABLE will create implicit sequence 'seq_test_id_seq'
for SERIAL column 'seq_test.id'
NOTICE: CREATE TABLE/UNIQUE will create implicit index
'seq_test_id_key' for table 'seq_test'
ERROR: Relation 'seq_test_id_seq' already exists
hope, developers would have their own reasons. but wish to know
that. thats it.

Bhuvaneswaran.
