How to rename a table inside a schema?

I'm using PostgreSQL 9.x, I want to rename a table. This SQL code:

CREATE TABLE new (id int);
ALTER TABLE new RENAME TO old;
DROP TABLE old;

renames the table correctly. But this SQL code:

CREATE SCHEMA domain;
CREATE TABLE domain.old (id int);
ALTER TABLE domain.old RENAME TO domain.new;

fails, with error:

ERROR: syntax error at or near "."

The "." underlined is the one between 'domain' and 'new'


Solution 1:

One way to do this:

ALTER TABLE domain.old RENAME TO new

Other way:

SET search_path TO domain;
ALTER TABLE old RENAME TO new;
