Load avarage is 4.26. A large query seems to overflow the system.
Type command "top" to make sure PostgreSQL is really at stake.

Then, modify /etc/init.d/postgresql to run PostgreSQL in debug mode:
postmaster ... -d debug-level

Restart PostgreSQL service entering:
"service postgresql restart"

This will log all queries and may help you understand what is going on.
