Dear All,
We have a database with no active relations on it. ( I.e. No tables or
Indexes exist as of now ).
But when we look at our base directory for this database, it's having many
relations pointing pg_type & pg_toast.
Curious to know the necessity of these objects and is this normal scenario ?
/pgDATA/base/102999
ls
1247
1247_fsm
1247_vm
13111
14702
3599
test_ora=# SELECT pg_filenode_relation(0,1247);
pg_filenode_relation
----------------------
pg_type
(1 row)
test_ora=# SELECT pg_filenode_relation(0,13111);
pg_filenode_relation
-------------------------
pg_toast.pg_toast_13109
(1 row)
test_ora=# SELECT pg_filenode_relation(0,14702);
pg_filenode_relation
-------------------------------
pg_toast.pg_toast_14697_index
(1 row)
test_ora=# SELECT pg_filenode_relation(0,3599);
pg_filenode_relation
------------------------------
pg_toast.pg_toast_3596_index

Some of the system catalogs have toast tables attached ...
