You can support the pgloader development by buying a Moral License. In return for that I will spend more time working on pgloader. There are several levels of sponsoring available, from the basic one to the custom one, allowing you to ask me to consider developing a custom feature that you need. The feature will be part of the single Open Source distribution of pgloader.
As it is a Moral License you are free to decide how much you want to contribute to the project financially. And of course you can change your mind and buy as many licenses as you want, without restrictions of time or seats etc. It's all about supporting an Open Source project!
When buying the license you will be offered to download the latest source bundle of pgloader. Also please note that the license does not cover any guarantee or contract and bears no legal authority, it only acknowledges that the purchaser made a payment to pgloader.
