Altering multiple column types

[Bharanee Rathna <deepfryed@xxxxxxxxx>]

Hi,

I'm encountering an issue altering multiple column types in a single ALTER TABLE

psql (12beta2, server 11.4)
Type "help" for help.

test=# create table users(id serial primary key, name varchar(255), age int, email varchar(255));
CREATE TABLE
test=# create index users_name_idx on users(name);
CREATE INDEX
test=# create index users_email_idx on users(email);
CREATE INDEX
test=# alter table users alter column name type text, alter column email type text;
psql: ERROR:  relation "users_name_idx" already exists
test=# alter table users alter column name type text;
ALTER TABLE
test=# alter table users alter column email type text;
ALTER TABLE

Is there a limitation I'm missing in the docs ?

Thanks
