INSERT INTO

[metov]

Describe the bug
For some statements, casing is not corrected. I have an example with INSERT INTO, but maybe it's others too.

To Reproduce
Formatting this produces no changes:

insert INTO foo (bar) VAluES (123);

Expected behavior
Casing should be normalized to what https://docs.sqlfmt.com/style says.

Actual behavior
Bad casing left as is.

Additional context
What is the output of sqlfmt --version?

sqlfmt, version 0.18.0

Also:

$ echo "insert INTO foo (bar) VAluES (123);" | sqlfmt - --check
1 file passed formatting check.
