On any of the "linuxlab" machines, type the following at the prompt:

   psql -h sql.csic.umd.edu

If your PostgreSQL user ID is different from your CSIC (linuxlab) ID,
you need to specify the PostgreSQL ID  as follows:

   psql -U username -h sql.csic.umd.edu

Once inside psql, type \h for help.

Remember to change your password.
