I'm looking at buying these drive for an entry level server to run a Postgress SQL database on.

That is read spead purformance so if you need fast read speads the faster the better.
However write speeds may be of some consideration dependeing on your systems requirements.
"an entry level server "
Please understand that the faster hard drives run much hotter than standard hard drives and will probably need better than an entry level servers cooling system.
absolutely NO difference in speed, with ANY mechanical HDD on the market today.  If you can't pump > approx 250 MB/sec reads or writes, then interface speed makes no difference.

Now some 6Gbit HDDs have better features than some 3Gbit drives, but I interpret your question as to whether you have any benefit running the same drive on 6 vs 3Gbit, and you are not using an expander with multiple drives sharing the same physical path.

If we move ahead it will be a RAID 10 with 4 of the above mentioned drives.
