Hi,
Back in the summer I started to write a pure PostgreSQL client library
for Go.
You can find it here:
http://github.com/lxn/go-pgsql
It is missing a few features, but what is there seems to work quite
well. I use it in a production web service running on a Linux box
where it is doing its job since a few weeks without trouble. It is
also doing fine on Windows, no idea about Mac though.
If you are working with PostgreSQL and Go, you may want to give it a
try.
Cheers
Alex
