Hi, the only remaining variation in the postgresql-10 builds is the `uname -m` information captured in pg_config.h: /usr/include/postgresql/10/server/pg_config.h: #define PG_VERSION_STR "PostgreSQL 10.4 (Debian 10.4-2.pgdg+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 7.3.0-18) 7.3.0, 64-bit" #define PG_VERSION_STR "PostgreSQL 10.4 (Debian 10.4-2.pgdg+1) on i686-pc-linux-gnu, compiled by gcc (Debian 7.3.0-18) 7.3.0, 64-bit" This information is also stored in Makefile.global, which is used by extension modules to configure themselves for the PostgreSQL server they are targetting: /usr/lib/postgresql/10/lib/pgxs/src/Makefile.global: host_tuple = x86_64-pc-linux-gnu host_os = linux-gnu host_cpu = x86_64 host_tuple = i686-pc-linux-gnu host_os = linux-gnu host_cpu = i686 I could probably remove the "on $host" part from PG_VERSION_STR, but Makefile.global is not so easy, because 3rd-party extensions might need the information. The difference stems from altering the kernel personality to report the i686 architecture name even on x86_64 aka amd64 systems. I think this is damaging an otherwise functional environment, i.e. systems should always be running with their native architecture (x86_64 on amd64, armv7l on armhf, etc) - otherwise the system is just broken. Chroots for related architectures should be using the corresponding architecture personality, and indeed, schroot can switch personality on entering chroots. Please don't vary kernel architecture personality for reproducibility testing. (Does (or did) this variation even catch real-world reproducibility problems in packages?)
