Error with Lexorank in error logs

[Rahul Aich [Nagra]]

Hi All

Context: JIRA 7.2.7 version.

I recently migrated our database from MySQL to PostGre SQL (unsing XML export import procedure).

After migration to PostGres i am observing this error in the logs everytime i create a new issue. 

I created the PostGreSQL database as described in the JIRA documentation.

I have also tried performing reindexing several times (even with deleting the caches folders) but has not worked.

Please help me identify what may be the root cause to this.
