Hi Wenjing,
Please refer this scenario , where reindex message is not coming next
time ( after reconnecting to database) for GTT
A)
--normal table
postgres=# create table nt(n int primary key);
CREATE TABLE
--GTT table
postgres=# create global temp table gtt(n int primary key);
CREATE TABLE
B)
--Reindex , normal table
postgres=# REINDEX (VERBOSE) TABLE nt;
INFO: index "nt_pkey" was reindexed
DETAIL: CPU: user: 0.00 s, system: 0.00 s, elapsed: 0.00 s
REINDEX
--reindex GTT table
postgres=# REINDEX (VERBOSE) TABLE gtt;
INFO: index "gtt_pkey" was reindexed
DETAIL: CPU: user: 0.00 s, system: 0.00 s, elapsed: 0.00 s
REINDEX
C)
--Reconnect to database
postgres=# \c
You are now connected to database "postgres" as user "tushar".

postgres=# REINDEX (VERBOSE) TABLE nt;
INFO: index "nt_pkey" was reindexed
