First today is a PostgreSQL community blogger note. Those of you who publish to the Planet PostgreSQL blog feed should take a look at the updated Planet PostgreSQL Policy. There’s a new clause there clarifying when it’s appropriate to mention promotions of commercial products like books. We’re trying to keep every blog post to the Planet feed focused on providing useful information, and just informing people of things like product giveaways doesn’t meet that standard. Several of these have gone by recently, but moving forward that will be considered a violation of the rules.
Speaking of what it’s safe to write about, I’ve published the next installment in my growing documentation set around disks that work well with PostgreSQL. Disk Plug Pull Testing covers how to use the diskchecker.pl program to validate your disks are working as expected for database use. I’m going to include that information in every disk review I do moving forward, even though I normally only talk about ones that pass this test. I think it’s that important to emphasize how vital this is. If someone recommends a drive and doesn’t explicitly tell you they run a plug pull test, be suspicious.
I’m also working on a series of Postgres Guides for how to setup related hardware like RAID controllers. So far there’s a long discussion of the LSI MegaRAID controllers there. I’m almost done with an Adaptec controller one too. It’s hard to figure all this out and the information needed changes regularly. I’m going to make this spot the primary place I maintain this data at, mainly so I can keep everything consistent.
