It's common for databases.
This is Percona's business model. They employ core pg/mysql developers and you can buy a support package from them. Same for enterprisedb. Pretty reasonably priced packages (like maybe $10k-ish/core IIRC) get you 24x7 support. I've only had to escalate issues once but inside 10 hours we got a pg core committer to debug some very strange vacuum behavior.
To clarify, I'm not saying that support contracts are uncommon. I'm saying that going out of their way to then additionally sponsor development of a specific testing tool on top of the support contract is not something I've heard companies do before, and it's pretty awesome!
