Athena DDL does not always respect /* ... */ block quotations. This is the case with (at least) `create external table ...` statements. Currently, if you try to run `create external table ...` statements, the following error is returned: `pyathena.error.OperationalError: FAILED: ParseException line 1:0 cannot recognize input near '/' '*' '{'` Here I monkey-patched _QueryComment.add to prepend "-- " to the `query_comment` and replace any newlines with " ". This allows the default `query_comment` to be added to `create external table` statements. We might want to do this so that dbt-labs/dbt-external-tables can add Athena support as is proposed in dbt-labs/dbt-external-tables/pull/133 Without this modification, the only way to run `dbt run-operation stage_external_sources --vars "ext_full_refresh: true"` without an error is to set `query_comment:` to nothing, a specific value, or a macro.
