PostgreSQL Conference Europe has just finished and I delivered two new presentations at the conference (a first for me). Postgres Scaling Opportunities summarizes scaling options, and Flexible Indexing with Postgres summarizes indexing options. I have been submitting these presentations to conferences for many months but this is the first conference to have chosen them. The talks were well attended and generated positive feedback.
The talks are more surveys rather than focussing on specific technologies. It might be beneficial for future conferences to have more survey-oriented talks, as many attendees are not Postgres experts.
I am now heading to Russia for two weeks, presenting in St. Petersburg and Moscow. I will also be visiting with our server developers in Russia who created some very significant features for Postgres 9.4.
