PostgreSQL Error: column am.amcanorder doesn't exist

I am working on CentOS release 6.8 (Final) based server without sudo access. I compiled PostgreSQL v9.6 beta 2.

When I am loading data using ant, I get am.amcanorder column doesn't exist error which I don't know how to fix.

I am following a tutorial to set up Intermine data warehousing system and I am on this step. The relevant error verbose is:
