PR Summary

• Introduced Verification for Table Existence in the Database
  We've put in place a safeguard that confirms whether a particular table has been set up in our Postgres chest of data before we make an effort to add any kind of information to it. This move helps us prevent unnecessary weary attempts to store in non-existent tables, leading to more efficient and error-free operations.
