UPDATED 2023: Find out how the PostgreSQL optimizer decides about “join pruning”. Improve performance, provide end users with simpler plans.
By coincidence I noticed that psql can produce perfect LaTeX code. How cool is that? We show you how to do it, with examples.

Test of performance using pgstrom with joins in PostgreSQL. Find out how pgstrom performs under different join conditions.
A more extensive look at pgstrom (a module to make use of GPUs for PostgreSQL). I was excited to see the first real performance data.
Some important work is also going into the PGStrom project, which is all about bringing the power of modern GPUs to PostgreSQL
Fuzzy search solves the problem of spelling errors in searches. The goal is really to make sure that users have a chance - even with typos.
