Created fix for 5475 (#5659)
Created fix for 5475
Currently in PGvector, we do not have any function that returns the
instance of an existing store. The from_documents always adds embeddings
and then returns the store. This fix is to add a function that will
return the instance of an existing store

Also changed the jupyter example for PGVector to show the example of
using the function

<!-- Remove if not applicable -->

Fixes # 5475
