connection_string is a hologres connection string.embedding_function any embedding function implementing
langchain.embeddings.base.Embeddings interface.ndims is the number of dimensions of the embedding output.table_name is the name of the table to store embeddings and data.
(default: langchain_pg_embedding)
pre_delete_table if True, will delete the table if it exists.
(default: False)
