If you do a full backup, does it complete in a normal manner and the usual time?
Have you tried doing a shutdown and restart of the database, or
possibly rebooting the server?
You may need to alter the database server settings to increase the
maximum query time.

1. Full backup taken without any issue. Checked it by restoring as another database in the same server. No Issues.
2. PG Service stopped and re-started. Re-booted the server also. Same issue.
3. PG is working with default settings only, that's set during installation time.

When the query was run in the restored database, in the same server machine, the query executed in a second. The same query, in original database, takes more than 15 min.
