I've fired up a 12beta2 and it works, either with psql 12 or psql 11.4 on linux.
What if you run the statements within another client (pgadmin, a java
client or something else)?

% psql -U postgres testdb
psql (12beta2)
Type "help" for help.

testdb=# create table users(id serial primary key, name varchar(255),
age int, email varchar(255));
CREATE TABLE
testdb=# create index users_email_idx on users(email);
CREATE INDEX
testdb=# alter table users alter column name type text, alter column
email type text;
ALTER TABLE
testdb=# SELECT version();
