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
