PostgreSQL No support for CREATE INDEX CONCURRENTLY

### SQLDelight Version

2.0.0

### SQLDelight Dialect

PostgreSQL

### Describe the Bug

Creating an index via `CREATE INDEX CONCURRENTLY` fails, even when I try to add the index via `CREATE INDEX` the migration fails.

It feels related with #4501 since it's a `CREATE` statement.

### Stacktrace

_No response_
