How to Force Reset a Postgres Auto Increment Counter to a Specific Value?

Force reset Postgres auto-increment counter

When using Postgres' auto-increment field, you may need to force its value to a specific number. After the previous attempts failed, let's dig deeper into how to reset the counters of the "product" table and its "Id" column.

Initially, we assume that the sequence name is the same as the table name. However, Postgres usually assigns sequence names using the format ${table}_${column}_seq. In this case, the sequence name should be "product_id_seq" instead of simply "product".

To reset the counter, use the following command:

<code class="language-sql">ALTER SEQUENCE product_id_seq RESTART WITH 1453;</code>

This modified command will successfully restart the sequence of the "Id" column of the "product" table, ensuring that the next inserted value will be 1453.

You can verify this by checking the sequence in the database using the ds command in psql. By inspecting the output of d product you can confirm the correct sequence name by checking the default constraint on the "Id" column.
