Bug: doesn't respect indentation size set in editor, and no option to set indentation size

[DeflateAwning]

In my settings.json file, I have:

{
    "[sql]": {
        "editor.defaultFormatter": "lea21st.vscode-sql-formatter",
        "editor.tabSize": 4,
        "editor.insertSpaces": true
    }
}

However, it still indents with 2 spaces.
