AttributeError: 'PgstatCollector' object has no attribute 'format'

Hi There,

There is some configuration to fix this error? pg_view work by less than 30 seconds, then crash:

[root@server ~]# pg_view -U postgres -p 9999
Traceback (most recent call last):
  File "/bin/pg_view", line 3432, in main
    loop(collectors, consumer, groups, output_method)

    curses.wrapper(do_loop, groups, output_method, collectors, consumer)
  File "/usr/lib64/python2.7/curses/wrapper.py", line 43, in wrapper
    return func(stdscr, *args, **kwds)

    st.refresh()
  File "/bin/pg_view", line 1196, in refresh
    proc_data = self._read_proc(pid, is_backend, is_active)
  File "/bin/pg_view", line 1253, in _read_proc
    result['uss'] = self._get_memory_usage(pid)
  File "/bin/pg_view", line 1275, in _get_memory_usage
    self.format(pid), e))
AttributeError: 'PgstatCollector' object has no attribute 'format'

About my enviroment:

[root@server ~]# python --version
Python 2.7.5
[root@server ~]# rpm -qa | grep postgresql
postgresql93-libs-9.3.14-1PGDG.rhel7.x86_64
postgresql93-contrib-9.3.14-1PGDG.rhel7.x86_64
postgresql93-9.3.14-1PGDG.rhel7.x86_64
postgresql93-server-9.3.14-1PGDG.rhel7.x86_64
[root@server ~]# rpm -qa | grep pg_view
pg_view-1.3.0-1.el7.noarch

Any ideias?

@sebastianwebber this is a typo, thank you for spotting it. The fix is in #67.

@a1exsh I ran into the same bug today in one of our data centers... 😞
