Hello, I noticed that the index (KEYWORD_INDEX_NAME) associated to a table in PgvectorDocumentStore (Haystack 2.0) is defined as global and later in the code it seems to raise an exception when one tries to create a second table, and as a consequence only one table per database can be used. Was it intentionally? What do you recommend me in case I need to use different tables to store data in order to be used to, for example, talk-to-documents?

Just in case, the exception is:
"haystack.document_stores.errors.errors.DocumentStoreError: Could not create keyword index on table."
