my case

• multi tenancy per schema
• extended AbstractDataSourceBasedMultiTenantConnectionProviderImpl to switch schema for each connection
• running schemaUpdate having set the schema with MetadataBuilder#applyImplicitSchemaName
• running schema-update on schema of the first tenant is ok
• schema-update on schema's of following tenant's are missing the 'create sequence ...' statements

SELECT relname FROM pg_class WHERE relkind='S' and pg_table_is_visible(oid)

works correctly; current workaround is to extend the Dialect for this

i might make a pull request to fix this
