The following documentation comment has been logged on the website:

Description:
Hello dear PostgreSQL family,
It is not entirely clear (to me) that ALTER TABLE statements with
comma-separated sub-commands are atomic. Despite of saying "perform X
actions in one operation" in one of the examples, it is not explicitly said
that the operation will be rolled back if one of the sub-commands fails.
From the examples, we have:
ALTER TABLE distributors
ALTER COLUMN address TYPE varchar(80),
ALTER COLUMN name TYPE varchar(100);
Will the `address` column type change rollback if the `ALTER COLUMN name
TYPE varchar(100)` subcommand fails?
Currently reading the docs for version 15.
Many thanks :)
