Server shutting down when using CASE keyword

[JacobDer]

Bug Description
When I attempt to use CASE in a query, the server shuts down right after I type the word and no more suggestions are made. If I press esc to return to normal mode I am shown a message Client 1 quit with exit code 2 and signal 0.

To Reproduce
Example reproduction:

1. With sqls active, type SELECT CASE W
2. Press esc to return to normal mode

Expected behavior
After typing SELECT CASE W, there should be suggestions for keywords which begin with 'W' and the server should not shut down unexepectedly.

Versions:

• OS Version: macOS 12
• sqls Version: latest

I found code like this will make it stackoverflow

select case
           when age>=25 WH

Just the word "case" is making the servers' stack to overflow. It can even just be in a string such as in this query.

INSERT INTO answers (answer) VALUES ("Camel case");

And the issue is still not even touched from what I see 😭
