PostgreSQL Create Index Error Relation already exists | Resolved

If you have been running into the “relation already exists” error in PostgreSQL, our experts are here to help.

This error usually occurs when we try to create a table, but there is already a table with the same name in the schema. PostgreSQL does not allow multiple tables with the same name in the same schema.

PostgreSQL Error: Relation already exists

Fortunately, we can easily resolve this issue with a little help from our experts.

How to resolve the error

1. Choose a Different Table Name:

   Since the error occurs due to an existing table with the same name, we have to select a different name for the table we are creating. We have to make sure the new name is unique within the schema and does not cause further conflicts.
2. Drop and Recreate the Table:

   However, if we want to replace an existing table with a new one, we can drop the existing table first and then create a new table. Our experts recommend being cautious when dropping tables since it deletes the data and structure related to the table. We can do this with the following steps:

   • First, we have to run the DROP TABLE statement to remove the existing table.
   • Then, we can create the new table with the CREATE TABLE statement.
   • Furthermore, we can check if there is an existing table with the same name. We can do this by querying the system catalog views to access information about existing tables.

With the above steps, we can resolve the “relation already exists” error when trying to create a table in PostgreSQL.
