**Why?**
The issue has been created on temporal-operator project (see:
https://github.com/alexandrevilain/temporal-operator/issues/402).
When we try to use the `temporal-sql-tool` `create` command with a
database name containing hyphen(s), even if escaped in command, it
throws the following error: `pq: syntax error at or near \"-\"`.
