Hi,
according to the documentation, the function pg_relation_filepath
"returns the entire file path name (relative to the database cluster's
data directory PGDATA) of the relation"
When my table are located in the pg_default tablespace, the gievn
relative path is correct
When my table are located on a specific tablespace, this function
returns incorrect dats such as :
pg_tblspc/25310/PG_9.1_201105231/16594/25311
only the "PG_9.1_201105231/16594/25311" is correct.
What does the "pg_tblspc/25310" do ???
How can I obtain the correct relative path ?
It is the correct relative path. It's relative to $PGDATA. Your
tablespace has the OID 25310. So, you have a symbolic link (or junction
if you are on Windows) named 25310 in your $PGDATA/pg_tblspc directory.
And PostgreSQL will access this table via the symbolic link. It really
uses this path: pg_tblspc/25310/PG_9.1_201105231/16594/25311
There's nothing wrong here.
yes, but I want to have the real path, not the symbolic PG path...
Do you know haw can I obtain it by a calssical SQL Query ?
