In PostgreSQL when I run the command
DROP VIEW IF EXISTS view_name;
I get the response:
View IF dropped.
Can anyone explain what this means? why the word ‘IF
‘ instead of a response like: View view_name dropped
?

That’s not what PostgreSQL does. Demo:
postgres=# create view view_name as select 1; CREATE VIEW postgres=# drop view if exists view_name; DROP VIEW postgres=# echo :SERVER_VERSION_NUM 110002 postgres=# drop view if exists view_name; NOTICE: view "view_name" does not exist, skipping DROP VIEW
Possibly you’re not using PostgreSQL proper, but rather a fork that has a different syntax for this operation. Check out the result of SELECT version();
.
