AFAIK if You don't use serial type You can just drop sequence and create
new with the same name. Of course You need increase start value of this
sequence to get right value at next insert.
I think there is no some secret conjunction between sequence and table
which use it, so if You replace Your sequence with new one of the same
name, there should be no problems.

CREATE SEQUENCE your_prev_seq START your_next_val_from_table;

Naturally if You use serial type - there may be some problems with such
work around.
    I don't understand, why You want to drop table - do You use serial
type?
