> If namespaces are enabled, we should check for the existence of the sequence schema before
creating the sequence. There are some sequences that are generated by Phoenix to manage indexes
over views which auto generate a schema name. Perhaps it'd be better if those used the SYSTEM
schema instead and prepended the sequence name with the previous schema name to ensure uniqueness.
