Thread: License question
Hello There,
I am looking to install PostgreSQL on a Microsoft Azure cloud VM for a product I am developing for business purpose. Is there a free version of PostgreSQL available which I can use without buying any licenses? In case I want to self install and manage the database? Just need guidance if I can install the available version from site for business purpose too or I must buy licenses? Will appreciate an appropriate related answer.
Thanks,
Prashant

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.
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.

What will it cost you or your employer if a "bug" in that software preventsaccess to, or worse yet, corrupts your data. 1) It is not "non-licensed", it is permissively licensed. 2) Not sure what the point of '... CONTINUING need for that software' is? If you have a process that depends on something to run then you have established a need. If you don't want that then don't start any project. > > 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?

Azure's Postgresql managed database handles all that (except off-hours support) for you, and there's much less off-hours support required (at least there was with AWS RDS Postgresql, so pressuming so with Azure, too).
Of course, OP just mentioned an Azure VM, so he'd have to do all that himself.
Using the Azure Postgresql managed database still means you'll have to think about archiving data, and properly configuring PG (mainly autovacuum parameters).

Thanks, Ron! Exactly my points!
I do not want to “discount” the community in ANY way. In fact, I’m a huge fan of Open Source, as long as everyone, including “management”, is bought into community support concept.
I’ve seen the “wrong side” of “What do you mean, ‘You posted something to the list’? Why can’t you CALL someone (and/or get someone logged in) RIGHT NOW?” discussions, usually “in the heat of battle”, a few too many times.
Of course, the flip side of this is “Whew – the community solved this before the <large software support organization> even got back to me”.
It comes down to being “fully informed”.

Open source PostgreSQL is and always has been free for any use.
If you're running it for real on Azure though, consider their managed service. If it's half as good as Amazon's RDS, it's probably worth a premium over the bare instance costs.

Not sure what your point is, you have to do all that with commercial software, too. And at least with open source you actually can find and patch bugs yourself, in theory, although you certainly don't have to, not with any major project.
Hi Christophe,
Thank you so much for the response. One of my client is also requesting details of licensed version of PostgreSQL. Could you please guide me cost of PostgreSQL license which they want to get installed on their (client’s) on premise server. Not sure how pricing works for enterprise license which have all associated support for enterprise. Also not sure if we can install on any supported license for on-Prem server or we have to buy specific server recommended by PostgreSQL. Will appreciate your guidance here.
Thanks,
Prashant

Hello, I think there is a fundamental misunderstanding here about how PostgreSQL's licensing works. You do not pay for the community version of PostgreSQL. The license specifically states it is available without a fee. It's free. No one collects money for the community version of PostgreSQL. There's no "enterprise" version of PostgreSQL that is provided by the community. It's just PostgreSQL. There are vendors which provide either commercial versions of PostgreSQL based on the community version, or which providecommercial support for PostgreSQL, but those are separate things from the PostgreSQL community version, and you wouldneed to talk to the individual companies to find out what their arrangements are. > On Nov 25, 2024, at 22:04, prashant sinha <prashantssiin@yahoo.co.in> wrote: > > Hi Christophe, > Thank you so much for the response.

Thank you Christophe I am very clear now. And post your email researched various vendors and will get in touch with them.
Thanks,

PostgreSQL is not a company. The PostgreSQL Global Development Group the body that oversees it is a non-profit.
