Hi All -

I would like to know if any one has instructions on how
to setup pg_standby, if so can you please share?

If you are on a *nix platform, I would suggest PITRTools which utilizes
pg_standby but gives you a more complete solution. Check out:

They should work on Solaris. It is just Python + Utilities you can
already get (like rsync and ssh).

When I execute the command cmd_archiver -I I am getting the following
response

I can't say anything about the application itself, but the cryptic
message means that the variable "filenames" is expected to be a
sequenced typed variable. A sequence in Python is a string, a list or
a tuple. To get the above error message requires the variable to be
something else, like an integer or something. One possible cause for
the problem is a configuration error. Perhaps a line contains a
non-string, as in foo = bar, instead of foo = "bar".

But again, I don't know about the application so I cannot give any
better guess, but the above is what the error is about.
