Describe the bug sorry before this my first time use data-diff and when i want running this i got error like this even though i try to install

• pip install psycopg2
• ‘pip install data-diff[postgresql]’ the result is still same

You can install it using 'pip install data-diff[postgresql]'.

can you explain what should i do?? thats my toml

[database.pg96]
driver = "postgresql"
user = "xxx"
password = "xxx"
database = "xxx"
host = "xxx"
port = 5432

[database.replicapg96]
driver = "postgresql"
user = "xxx"
password = "xxx"
database = "xxx"
host = "xxx"
port = 5432


[run.default]
update_column = "updated_at"
verbose = true

[run.test_diff]
1.database = "xxx"
1.table = "xxx"
2.database = "xxx"
2.table = "xxx"

Sorry I replied but looks like it didn’t post. Yes, if that’s the entire output, it means there is no difference.
