@vrms Last I heard (March 2025) the maintainers chose not to support PostgreSQL. Please see thread here.
I’ve personally been running Postgres in my own fork for over 5 months in a production enviornment…
…however. Because I knew my work would never go into mainstream Frappe Framework? I did it very hastily. Took lots of shortcuts. Didn’t spend much time on inline documentation. And that same fork contains about a hundred modifications that have nothing to do with Postgres.
So it’s quite a mess. But if you want to take a peek, and copy + paste what looks interesting, then of course you’re welcome to do so.
