I've created a table like so:
create table doki_data_item2 (like doki_data_item including defaults);
but this new table uses the same sequence as the old table.
So two questions:
- How can I copy and table and the necessary sequences easily?
- How can I replace a sequence on one table with another sequence?

Why don't you create a new sequence:
create sequence new_sequence;
Then create the new table
create table doki_data_item2 (like doki_data_item including defaults);
Finally modify the column that is using the old sequence to use the new one:
alter table doki_data_item2 alter column seq_column set default nextval('new_sequence');
You can obviously set various parameters for the newly created sequence to suit your needs.
