PostgreSQL Function “ARRAY_APPEND” Does Not Exist: Fix

The array_append function in PostgreSQL is a built-in function that enables us to append one or more elements to an array’s end. The array to which we wish to attach elements is the first argument, and the element or elements we want to append are the second. The basic syntax is as follows:

Here, array is the array to which we want to append elements and value is the value or values we want to append to the end of the array. We can specify a single value or an array of values.

Let’s look at some of the possible causes and corresponding solutions for the error.

1. Function Signature: We must ensure we’re using the correct function signature.

2. Schema/Namespace: The PostgreSQL standard library includes the array_append function, which is to be accessible in the public schema. Make sure we are not in a different schema or namespace where the function might not be available if we are having problems.

3. Permissions: Verify that we have the right permissions before performing this procedure. Lack of privileges may be the cause of the “function does not exist” issue we are experiencing.

4. Database Version: The functionality of PostgreSQL can vary a little depending on the database version. Ensure that the array_append function is supported by the PostgreSQL version we are using.
