I’m looking forward to the Seattle PostgreSQL User Group meetup this Thursday (June 20, 2019) at 5:30pm! We’re going to get an early sneak peek at what’s coming later this year in PostgreSQL’s next major release. The current velocity of development in this open source community is staggering and this is an exciting and valuable opportunity to keep up with where PostgreSQL is going next.

One thing that’s a bit unusual about this meetup is the new location and late timing of the announcement. I think it’s worth a quick blog post to mention the location: for some people this new location might be a little more accessible than the normal spot (over at the Fred Hutch).

I have been wondering about open source projects for a while. I’ve talked to quite a few people about it, and still don’t really understand some of it. So I decided to write a post about my thoughts regarding this issue.

I’m not going to talk (or even mention) specific projects, but it is very interesting to me how these projects run.

The fsfreeze command, is used to suspend and resume access to a file system. This allows consistent snapshots to be taken of the filesystem. fsfreeze supports Ext3/4, ReiserFS, JFS and XFS.

A filesystem can be frozen using following command:

Now if you are writing to this filesystem, the process/command will be stuck. For example, following command will be stuck in D (UNINTERUPTEBLE_SLEEP) state:

Only after the filesystem is unfreezed using the following command, can it continue:
