Looks good. The patch uses the same phrase for “if exists” as the doc of “drop publication”. And I verified that a
noticeis issued:
```
evantest=# drop publication if exists aaa;
NOTICE: publication "aaa" does not exist, skipping
DROP PUBLICATION
evantest=# drop subscription if exists aaa;
NOTICE: subscription "aaa" does not exist, skipping
DROP SUBSCRIPTION
```
