Thanks for your reply Adrian Klaver,

Yes, I have the tablespace. It is not located in the default data directory.
It is comes under new directory

Please expand on this:

1) Did it change location when you moved the data directory?

2) If so where was it previously and where is it now?


Where I am going with this:

https://www.postgresql.org/docs/current/manage-ag-tablespaces.html

"PostgreSQL makes use of symbolic links to simplify the implementation of tablespaces. This means that tablespaces can be used only on systems that support symbolic links.

The directory $PGDATA/pg_tblspc contains symbolic links that point to each of the non-built-in tablespaces defined in the cluster. Although not recommended, it is possible to adjust the tablespace layout by hand by redefining these links. Under no circumstances perform this operation while the server is running. Note that in PostgreSQL 9.1 and earlier you will also need to update the pg_tablespace catalog with the new locations. (If you do not, pg_dump will continue to output the old tablespace locations.)"





Thanks,
Karthick Ramu
