Hi Wenjing,
Please check the below scenario shows different error message with "DROP
TABLE gtt;" for gtt with and without index.
*-- Session1:*postgres=# create global temporary table gtt1 (c1 int);
CREATE TABLE
postgres=# create global temporary table gtt2 (c1 int);
CREATE TABLE
postgres=# create index idx2 on gtt2(c1);
CREATE INDEX
*-- Session2:*postgres=# drop table gtt1;
ERROR: can not drop relation gtt1 when other backend attached this global
temp table
postgres=# drop table gtt2;
ERROR: can not drop index gtt2 when other backend attached this global
temp table.
