PG version recommendation

Hi:

I'm going to be requesting a PG instance supported by an IT team in a large corp.  They will be creating the server as a VM.  We will be loading the DB using scripts (perl/dbi) on linux, possibly using bulk loading techniques if that's required.  Queries will come from both linux and the web, but typically the number of concurrent users will be on the order of 10 reads, maybe a couple writers.  < 1T total disk, no partitioning.  I will be requesting PITR.  

I need to pick a PG version in my request.  I want something that will be stable and reliable while, of course, being able to perform well.  What would be a good choice for PG version ?

Also, since the server will be a VM, are there any special recommendations/suggestions might I forward in the request (install options, tuning options, other) ?

Thanks !
