Yes, you require a license.  However, luckily for you, the license is
provided for any purpose, without fee, and without a written agreement.
The COPYRIGHT file in the source distribution contains the details.
You can use the software standalone or in cluster configuration, as you
see fit.  In short, you don't need to worry about it.

However, this doesn't necessarily apply to other software packages
derived from PostgreSQL itself, or those that work in conjunction with
it, such as Postgres extensions, admin interfaces, GUIs, monitoring
packages, etc.  You'll have to seek clarification on each such software
package that you intend to use.

Clarification Needed on Postgresql License Requirement for Hybrid Environment Cluster Configuration

[Prasanna Chavan]

Hi,

I hope this email finds you well. I am reaching out to seek clarification on a 
matter regarding the configuration of a cluster in a hybrid environment.
Specifically, I am wondering whether we require a PostgreSQL license for 
setting up a cluster in such an environment. Could you kindly provide some 
guidance or clarification on this matter?
Your expertise and insights on this issue would be greatly appreciated. Thank 
you in advance for your assistance.
Looking forward to your prompt response.
Best regards,
Prasanna

I believe that is answered further down on the page:

There are no plans to change the PostgreSQL License or release

That makes a lot of sense. A head gasket costs about $25.00.
*Installing* the head gasket costs well over a thousand. As long as the
customer has the option to install it himself, you're selling your
services.

If you've modified PostgreSQL, as long as you offer the source code to
the customer and say "good luck installing it by yourself",  you can
charge to install it without breaking even the GNU GPL.

My understanding is the PostgreSQL license is more like the MIT
license, which actually allows one to modify the code and claim it as
proprietary.

That's just really not true.  There is nothing that prohibits
you from selling Postgresql.  I mean, it's not a great business
model because you can get it for free, but there's nothing that
stops you from doing it.


Quoting Adrian Klaver in this thread from about eight hours ago:
"You cannot (legitimately) charge the pharmacist for any part
PostgresQL."


Actually that's Rob Sargent you're quoting. Adrian took issue with
that statement, as do I.  While Google isn't finding me anything that
says "Yes, you can sell Postgresql," here are a few points:

  * Point to anything in the license wording that says you can't
charge money to distribute Postgresql.  You can't.

  * Even software licensed under the GPL, which is a considerably
more restrictive license, can be sold.  The free software folks
consider the right to sell as one of the freedoms associated with
free software.  [1]

  * The Postgresql license page says it is "a liberal Open Source
license, similar to the BSD or MIT licenses." [2] The MIT license
itself explicitly states that it grants rights to "sell copies of
the software."



How do you sell what you don't own?


You can do so because the owners have granted you the right to do so.  
They were just good enough to not charge you money for it.


Maybe I'm too literal.  I understand:

1. selling physical media that software comes on,
2. selling access to a server where the software resides, and
3. selling a license to use software.

Selling a license to Postgres is worse than selling bottled water, because 
at least the bottled water adds a few chemicals for taste, and they put it 
in conveniently sized and shaped bottles.

your web-app, any documentation of your web-app and schema, any

Why not?

Pretty sure that is what third parties are doing with their forks of Postgres.


I see your point, but aren’t they in essence charging for their efforts in 
making, managing their fork.  There are plenty of vendors, for a time I was 
one, who happily apply a schema to which ever database the client supplied 
(mssql, ora, pg in my case).


In general that pretty much applies to a lot of software that has price. 
You don't actually own the software, just a paid license to use it. I'm 
not saying whether it is a good idea or not, just that it is possible.

I take it that the OP has an app/dataset on top of PG he/she wishes to market 
(and protect).  Perfectly legit, no? Not clear if there is a desire to disable 
direct db access.

 This means that you don't have to pay a fee or sign a written agreement
 to use, copy, modify, and distribute this software and its documentation
 for any purpose. It doesn't say that you can't charge a fee for
 distributing (although why anybody would pay you for something they can
 download themselves for free I don't know).

This means that you don't have to pay a fee or sign a written agreement
to use, copy, modify, and distribute this software and its documentation
for any purpose. It doesn't say that you can't charge a fee for
distributing (although why anybody would pay you for something they can
download themselves for free I don't know).

Re: PostgreSQL License

[Ashkar Dev]

Thank you all,
but it is saying (without fee)
if I create a database with it to work with Web Application if want to sell
it so the buyer must have the PostgreSQL installed in his device to work
offline right?
"Permission to use, copy, modify, and distribute this software and its
documentation for any purpose, *without fee*, and without a written
agreement is hereby granted, provided that the above copyright notice and
this paragraph and the following two paragraphs appear in all copies."

Yes.

You only have to make sure that the original license text is included
in your license.  This does not limit what you are allowed to do with
the software.
