Multicorn2.org is the new home of the old Multicorn project. We recommend you use the orioginal Multicorn project for versions 12 and earlier of PostgreSQL. Our aim is to build an active and inclusive community to carry on with the good work done by Segfault and others.
We support PostgreSQL 13 thru (coming soon) 15 w/ Python 3.6+. Our highest priority is getting Multicorn2 to work as well with PostgreSQL 13, 14 & 15, as it did w/ Python 2.6+ in versions of Postgres.
