> Given two tables in the same schema, we can't create an index with the same name for both tables. In other words, the following code leads to an error - which is good.
> {code}
> CREATE INDEX IDX on T1 (COL);
> CREATE INDEX IDX on T2 (COL);
> {code}
> If used with `IF NOT EXISTS`, the queries pass. It might be OK or not - one needs to look into SQL spec to check if the second operation should be a no-op (because IDX exists) or fail (because IDX exists for a different table, so the caller is probably doing something wrong)
> {code}
> CREATE INDEX IDX on T1 (COL);
> CREATE INDEX IF NOT EXISTS IDX on T2 (COL);
> {code}
> However, if persistence is enabled, the node will fail to restart complaining about duplicate index names.

> It looks like the second index (on T2) is partially created after all.
> Need to either block index creation by `CREATE INDEX IF NOT EXISTS` completely, or just fail that query when the table names don't match (if SQL spec allows it).
