I can't wait until people find its limits!

I can't wait until people find its limits... in production!

Did you know that Postgres has a max table size of 32TB? Its really really fun to find that out the Wednesday evening before Thanksgiving.

Make sure to prune old data from your tables. This one got to this limit because it eventually got too large that queries to delete old data would time out... so it just kept growing.

I just put a maximum Postgres table size I’m willing to manage in my employment contract. By the time we’re measuring in Terabytes I’m out of there.

it is partitioned underneath with limit of 32TB for single partition. (hello ctid). there could be many of them.

[victorbjorklund]

Wow. That is still pretty large for one table.

Everyone has a testing environment. Some people even have separate production environments.

Production is the best testing environment after all.

For 90%+ of our customers (small-to-mid sized US financial institutions), production is the only environment available to work with.

For the other 10%, we take them aside and politely explain that they almost certainly have an unusable staging environment per the scope of our B2B project.

Testing in production is a wonderful path if you are comfortable talking to business people and making lots of compromises.

I'm going to guess that Amazon.com will be one of the first to find all of the limits.
