PGBR is the major portuguese-speaking PostgreSQL conference. It is the biggest PostgreSQL event in Americas. We're in the fifth edition. This year the conference will be outside Sao Paulo State. It will take place at Amazon Area (Porto Velho, Rondônia). It is scheduled to be held from August 15 to 17, 2013.
I was at Porto Velho for a PGDay 2009 -- invited by Luis Bueno. It was a unique opportunity to meet people that I've never imagined that was using Postgres in their projects. Of course, I can't miss a ride in Rio Madeira waters and relish a typical fish in a sauce.
