it is working on my 11.4 with psql 11.4. Could it be a problem of psql
version 12? Can you try again with a psql "stable"?

testdb=> create table users(id serial primary key, name varchar(255),
age int, email varchar(255));
CREATE TABLE
testdb=> alter table users alter column name type text, alter column
email type text;
ALTER TABLE
testdb=> drop table users;
DROP TABLE
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=> \d users
Table "public.users"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+-----------------------------------
id | integer | | not null | nextval('users_id_seq'::regclass)
name | text | | |
age | integer | | |
email | text | | |
Indexes:
"users_pkey" PRIMARY KEY, btree (id)
"users_email_idx" btree (email)

testdb=> select version();
version
