Thanks wenjing
Please refer this scenario , where getting an error while performing cluster o/p
1)
X terminal -
postgres=# create global temp table f(n int);
CREATE TABLE
Y Terminal -
postgres=# create index index12 on f(n);
CREATE INDEX
postgres=# \q
X terminal -
postgres=# reindex index index12;
REINDEX
postgres=# cluster f using index12;
ERROR: cannot cluster on invalid index "index12"
postgres=# drop index index12;
DROP INDEX
if this is an expected , could we try to make the error message more simpler, if possible.
Another issue -
X terminal -
postgres=# create global temp table f11(n int);
CREATE TABLE
postgres=# create index ind1 on f11(n);
CREATE INDEX
postgres=# create index ind2 on f11(n);
CREATE INDEX
postgres=#
Y terminal -
postgres=# drop table f11;
ERROR: cannot drop index ind2 or global temporary table f11
HINT: Because the index is created on the global temporary table and other backend attached it.
postgres=#
it is only mentioning about ind2 index but what about ind1 and what if - they have lots of indexes ?
i think - we should not mix index information while dropping the table and vice versa.
