Business as usual: somebody funds it--not necessarily the developers--in exchange for a slice of the pie if the project is successful.
If it will be succesfull, time will tell. But serverless postgres would be really sweet to have. Hell, AWS itself should be funding this project. I run my Postgres for hobby projects at home because AWS Aurora serverless postgres is very expensive and doesn't scale down to zero. I wouldn't mind paying a dollar or two for storage the months I don't use that project, and a little more when I actually need to query my databases. At work, my $$$$$$ employer pays $$-employees to poke at $$$-devs who forget to shut down an Aurora serverless Postgres.
