Function containsSelectStar

src/db/utils.ts:62–71

* Detect column wildcards (`SELECT *` or `SELECT t.*`) anywhere in the query, * including inside subqueries. Aggregate forms like `COUNT(*)` are *not* * flagged because the parser represents those as a `star`-typed expression * argument rather than a `column_ref` with column `"*"`. * * Returns

(sql: string)

 * path. We don't want a parser hiccup to block otherwise valid queries here.
