When trying to use "DROP VIEW IF EXISTS x" while a table named "x" exists, the DROP statement raises an "Error: x is not a view".
The documentation says about the "IF EXISTS" clause:
> Do not throw an error if the view does not exist. A notice is issued in this case.
Imho, there shouldn't be an error if the view does not exist regardless of whether or not a table with this name exists. The observed behavior is contrary to the sense of the "IF EXISTS" clause as one would have to check whether a table with the desired name exists before using "DROP VIEW IF EXISTS". But then you could directly check whether or not the view itself exists.
This thread from 2018 illustrates the current state of the discussion:
