We have a new architecture on apt.postgresql.org: Loongson loong64, a Chinese processor architecture.
The build host for the architecture is running on a Loongson 3B6000 board provided by the loongfans.cn community.
Bootstrapping the PostgreSQL packages was completed earlier this month and everything is in place to be used via apt.postgresql.org.
The exception is the GIS stack of packages (postgis, pgrouting, mobilitydb, pgsql-ogr-fdw) which are currently still waiting for the next postgis release.
Enjoy, Christoph
