Let us be nice to users. Attached is a very small patch which adds a
simple HINT on this initial failure, for submission to the next
commitfest.

  sh> ./pgbench foo
  ERROR:  relation "pgbench_branches" does not exist
  LINE 1: select count(*) from pgbench_branches
                               ^
  HINT: is "foo" the right database? did you initialize first (pgbench -i)?
