RE: License question - Mailing list pgsql-general

Christophe is spot on when it comes to the PostgreSQL software.

Not trying to be "snarky" or condescending, but there are some other considerations.   "Open Source" or "Free" does not
mean"without cost". 

No matter where you decide to host the software, there will be storage, compute, and network costs, not only to support
thesoftware itself, but also the data you store. 

With respect to the data, since you or your employer have decided to persistently store the data in a database, I would
presumethe data, and more importantly, access to that data, has value. 

It seems from the original post that you've decided to pay someone (a cloud vendor) to "take care" of the storage,
network,and compute "services".  That's great! 

But, what about that "non-licensed" software?   Once you use that software to store and access your data, you have
createda CONTINUING need for that software.   What will it cost you or your employer if a "bug" in that software
preventsaccess to, or worse yet, corrupts your data. 

Are you willing to sign up for "maintaining" PostgreSQL in your environment, INCLUDING things like patching, finding
andfixing bugs, upgrades, backup and recovery, and off-hours support?  If you or your employer have any concerns about
this,and IHMO, you should, you might want to consider a "licensed and supported" version of PostgreSQL.  There are
severalout there, including EDB and others.  Even the big cloud vendors have "support plans" for PostgreSQL. 

Oh, and don't forget, a backup only as good as the last time you tested a restore.

PostgreSQL itself is an open source project distributed under a very permissive license:

        https://www.postgresql.org/about/licence/

No payment is required to download and run it.
