That's right, if the tables are in default tablespace, those columns will be blank, if any of the table created under any of the tablespace then it will show up.
Eg:- postgres=# show default_tablespace ; (this would be blank becz am in pg_default/pg_global) default_tablespace -------------------- (1 row) postgres=# create table foo(id int); CREATE TABLE postgres=# select * from pg_tables where tablename='foo'; -[ RECORD 1 ]--------- schemaname | public tablename | foo tableowner | postgres tablespace | hasindexes | f hasrules | f hastriggers | f Now I have the table in one of my tablespace. postgres=#create table tab_test(id int) tablespace t1; Expanded display is on. postgres=# select * from pg_tables where tablename='tab_test'; -[ RECORD 1 ]--------- schemaname | public tablename | tab_test tableowner | postgres *tablespace | t1* hasindexes | f hasrules | f hastriggers | f If you want to know the tablespace default information, you can try with this query. select spcname, case spcname when 'pg_default' then (select setting from pg_settings where name = 'data_directory')||'/base' when 'pg_global' then (select setting from pg_settings where name = 'data_directory')||'/global' else spclocation end from pg_tablespace; To get the exact table's and its tablespace's below query will work. select relname,reltablespace from pg_class where reltablespace in(select oid from pg_tablespace where spcname not in ('pg_default','pg_global')); --- Best Regards, Raghavendra EnterpriseDB Corporation Blog: http://raghavt.blogspot.com/ On Mon, Jun 20, 2011 at 11:40 PM, hyelluas <helen_yell...@mcafee.com> wrote: > thank you Greg, > > here is what I get, I createed view as you suggested. > I'm not sure why tablespace column is empty > > profiler1=# select * from pg_tables where schemaname ='public' limit 10; > schemaname | tablename | tableowner | tablespace | > hasindexes > | hasrules | hastri > ers > > ------------+-------------------------+------------+------------+------------+----------+------- > ---- > public | ttt | postgres | > | f | f | f > public | summ_hrly_1514609 | postgres | | t > | f | f > public | summ_5min_1514610 | postgres | | t > | f | f > public | exp_cnt | postgres | > | f | f | f > public | auth_type | postgres | > | > t | f | f > public | druid_mapping | postgres | | > t | f | f > public | application_category | postgres | | t > | f | f > public | application_risk | postgres | > | t | f | f > public | policy_history | postgres | > | t | f | f > public | datasource | postgres | > | > t | f | f > (10 rows) > > > thank you. > Helen > > > -- > View this message in context: > http://postgresql.1045698.n5.nabble.com/how-to-find-a-tablespace-for-the-table-tp4500200p4507266.html > Sent from the PostgreSQL - general mailing list archive at Nabble.com. > > -- > Sent via pgsql-general mailing list (pgsql-general@postgresql.org) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-general >
