The clauses SET TABLESPACE and ALL IN TABLESPACE are supported in ALTER MATERIALIZED VIEW for a long time, and they behave mostly like ALTER TABLE by reusing the same code paths, but there were zero tests for them. This commit closes the gap with new tests in tablespace.sql. Author: Yugo Nagata Discussion: https://postgr.es/m/20220316133337.5dc9740abfa24c25ec9f67f5@sraoss.co.jp
