LEFT JOIN pg_tablespace AS t ON c.reltablespace=t.oid
WHERE
c.relname='pg_class';
I was at the same point, doing another way :
COALESCE(spclocation, setting) ||
CASE
WHEN T.spcname <> 'pg_global'
THEN SUBSTRING(REPLACE(pg_relation_filepath(C.oid),
'pg_tblspc/', ''),
POSITION('/' IN
REPLACE(pg_relation_filepath(C.oid), 'pg_tblspc/', '')),
CHARACTER_LENGTH(REPLACE(pg_relation_filepath(C.oid), 'pg_tblspc/', '')))
WHEN T.spcname = 'pg_global'
THEN (SELECT setting FROM pg_settings WHERE name =
'data_directory')
|| '/' || pg_relation_filepath(C.oid)
ELSE '/' || pg_relation_filepath(C.oid) END AS location
... using pg_setting
This returns the same datas
