The cypher function terminated the connection due to missing query argument

[mohayu22]

Bug Description:
I ran a query on my graph using the following code:
SELECT * FROM cypher('demo_graph') as (v agtype);

However, I forgot to include the query argument for the Cypher function. As a result, the server closed the connection unexpectedly, and I received the error message.

server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.

Expected Result:
I was expecting an exception to be raised (throw an Error) instead of the connection being terminated.

Setup:
Command Line: start postgres with pg_ctl --> connect to database with psql

Environment:
PostgreSQL v11.18 | Latest Apache Age | Ubuntu 20.04.5 LTS

@mohayu22 Thank you for catching this. It appears that when I added in some code for driver integration, an edge case was overlooked. I will correct it.
