ktravis commented on issue #4285: Import CSV File Into PosgreSQL Table. Error: 
password authentication failed
   I was experiencing the same issue and did some digging. It seems that as of 
#4298, the call to `create_engine` within `create_table_from_csv` [located 
 is using `sqlalchemy_uri` to create a new SQLAlchemy engine. This works as

               'df': df,

               'con': create_engine(form.con.data.sqlalchemy_uri_decrypted, 
               'schema': form.schema.data,
               'if_exists': form.if_exists.data,
               'index': form.index.data,
               'index_label': form.index_label.data,
