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 TABLEIs there a limitation I'm missing in the docs ?
https://www.postgresql.org/docs/11/sql-altertable.html
Thanks
