There are some interesting statistics in the survey from Matt Aslett of the 451 Group (451 Group survey highlights user concerns over Oracle’s proposed ownership of MySQL).
One of the stats that stands out in the write up is: “PostgreSQL usage is also expected to grow, from 27.1% of all users today to 30.5% in 2011″.
This statistic in particular prompted a flurry of calls from partners and customers over the past few days excited about the relative penetration of Postgres indicated in this survey.
