Remove trailing commas for Puppet 2.7.1 compatibility

[jarib]

Thanks for creating this module!

I had to remove a few trailing commas to make things run on 2.7.1 (which is the default in Ubuntu 11.10).

Merging even though I love trailing commas :-)

For reference, support for trailing commas in argument lists was added in Puppet 2.7.8, released 2011-12-08.

Thanks! Turns out there are other issues on Ubuntu 11.10 as well. I had to add a few symlinks to make things run:

/etc/postgresql/main -> /etc/postgresql/9.1/main
/usr/lib/postgresql/{bin,lib} -> /usr/lib/postgresql/9.1/{bin,lib}

It's not an issue for me personally as we'll upgrade to Ubuntu 12 soon anyway, so if you don't want to support 11.10 (and revert this), that's cool.
