Title:
  pgdump plugin does not handle missing commands gracefully

Status in Holland Backup Framework:
  New

Bug description:
  Like most holland plugins, pg_dump runs commands through subprocess
  rather than via a shell.  If a command is not found, subprocess raises
  an OSError with errno = ENOENT.  This results in a messy and confusing
  failure message.

  These invocations should be wrapped around a try/except to detect
  these cases and fail cleanly.

  This particular case is common with Postgres on RHEL/Cent as newer
  versions installed from yum.postgresql.org are probably going to put
  their tools in /usr/pgsql-{version}/bin/ and not necessarily be in the
  path.   holland's default path doesn't pick these up automatically.
