In PostgreSQL, one can drop a temporary table by the use of the DROP TABLE statement.

Syntax: DROP TABLE temp_table_name;

Unlike the CREATE TABLE statement, the DROP TABLE statement does not have the TEMP or TEMPORARY keyword created specifically for temporary tables. To demonstrate the process of dropping a temporary table let's first create one by following the below instructions. First, we create a sample database(say, test) to add a temporary table using the below statement:

CREATE DATABASE test;

After creating the database we switch into it using the following command:

\c test;

Now we add a temporary table (say, mytemp) to the test database as below:

CREATE TABLE mytemp(c INT);

Verify if the table has been created using the below statement:

SELECT * FROM mytemp;

It should show you the below table: Now that our temporary table is created we remove it in the below example. Example: We use the DROP TABLE statement inside the database test as follows to drop the temporary table:

DROP TABLE mytemp;

Now we verify if the table has been removed successfully using the below statement:

SELECT * FROM mytemp;

Output: The above-shown error raised by PostgreSQL shows that the mytemp table doesn't exist anymore.
