There isn't, really. It's very liberally licensed, and you're free to distribute it.
However, as someone who writes "private closed commercial software" that uses postgresql as a backend I'd fairly
stronglysuggest that you at least provide end users the opportunity to use their own installation of postgresql if they
wantto. "Hiding" the existence of postgresql in your package doesn't magically make it as low maintenance as sqlite, so
userswill still know it's there and might want to point your app at their supported, tuned installation instead. (And
maywant to fire up psql to see what's in there - you'll get happier customers if you put connection info and a database
schemadiagram in your docs than if you try to hide your use of a database).
I no longer distribute postgresql bundled with the app at all. On platforms with decent package managers I just ship a
packagethat relies on the OS-installed postgresql. For other environments I provide a package for the app, and a
separatepackage with postgresql.
If you do decide to distribute postgresql with your app (by bundling the enterprisedb installer as part of a windows
appinstaller, say) be very careful that it's configured to not clash with a used-installed copy of postgresql.
Cheers,
Steve
