I disagree. {…} means “choose exactly one of the following alternatives”, but not for grouping for repetition.

For example:

```
GRANT { { SELECT | INSERT | UPDATE | DELETE | TRUNCATE | REFERENCES | TRIGGER | MAINTAIN }
[, ...] | ALL [ PRIVILEGES ] }
ON { [ TABLE ] table_name [, ...]
| ALL TABLES IN SCHEMA schema_name [, ...] }
TO role_specification [, ...] [ WITH GRANT OPTION ]
[ GRANTED BY role_specification ]
```

The two levels of {} are all for alternatives.

So, I think the correct way is like:

```
TABLE table_spec [, TABLE table_spec … ]
```
