For every serial/bigserial you have a table that should be named something like 
<table_name>_<column_name>_seq where table_name is the name of the table in 
which the serial is used and column_name is the name of the column that is the 
serial. It can be that it will be only <table_name>_seq. But depends on how you 
set up the table.
The table should look something like this:

 sequence_name | last_value | increment_by | ...
-------------------+------------+---------------+ ...
    album_seq     |        461   |            1      | ...

for what you want you will need to change the last_value column.
