Now is the perfect time to get involved in Postgres development!
Think you’re not qualified to review patches? Think again!
From the Reviewing a Patch documentation:
If you can apply a patch and you can use the new feature, you’re already qualified to start reviewing it.
We will formally kick off a reviewfest on June 15.
We will assign reviewers and get all the patches that are queued up for 9.1 reviewed while the final touches are being applied to the 9.0 release. Have a look at Review A Patch guidelines for information about how to conduct your review. We also have a mailing list to track and recruit reviewers – pgsql-rrreviewers. (The extra R’s are for ’round-robin’)
