Problem accessing database on nodes of a cluster

Hello admins,

I am having problems accessing a database on the nodes of a cluster. I am
working on a project that is supposed to distribute data on the nodes of a
beowulf cluster and then run queries in parallel on the nodes.

I am able to create and access a database on the master node. But when I
try to access the database on a slave node, I get the following error:

psql: FATAL: database "db001", OID 1198223, has disappeared from pg_database
[1]+ Exit 1 postmaster -p 9012 -D
/home/gayatri/postgres/data >logfile27 2>&1

I would really appreciate any help in this matter.

Thank you.

Sincerely,
Kashif Riaz
