Review Comment:
The `LIKE` keyword in the `SHOW` commands is actually *case-insensitive*
according to the docs
(https://docs.snowflake.com/en/sql-reference/sql/show-tables). But it does
treat underscores like a `LIKE` comparison, though we do say in the docs that
the arguments for "catalog" and such are treated as patterns if they include
wildcards like `_` and `%`.
