Hmm. No Ubuntu here and I don't know the answer (CC Christoph). Can you show exactly where the package is coming from, what pg_config outputs. For what it's worth, it does look like it's enabled in the Ubuntu aarch64 packages from apt.postgresql.org, according to a quick look using caveman techniques: $ curl -sO http://apt.postgresql.org/pub/repos/apt/pool/14/p/postgresql-14/postgresql-14_14~beta3-1.pgdg+1_arm64.deb $ ar x postgresql-14_14~beta3-1.pgdg+1_arm64.deb $ tar xf data.tar.xz $ strings usr/lib/postgresql/14/bin/postgres | grep 'with-llvm' '--build=aarch64-linux-gnu' '--prefix=/usr' '--includedir=${prefix}/include' '--mandir=${prefix}/share/man' '--infodir=${prefix}/share/info' '--sysconfdir=/etc' '--localstatedir=/var' '--disable-option-checking' '--disable-silent-rules' '--libdir=${prefix}/lib/aarch64-linux-gnu' '--runstatedir=/run' '--disable-maintainer-mode' '--disable-dependency-tracking' '--with-icu' '--with-tcl' '--with-perl' '--with-python' '--with-pam' '--with-openssl' '--with-libxml' '--with-libxslt' 'PYTHON=/usr/bin/python3' '--mandir=/usr/share/postgresql/14/man' '--docdir=/usr/share/doc/postgresql-doc-14' '--sysconfdir=/etc/postgresql-common' '--datarootdir=/usr/share/' '--datadir=/usr/share/postgresql/14' '--bindir=/usr/lib/postgresql/14/bin' '--libdir=/usr/lib/aarch64-linux-gnu/' '--libexecdir=/usr/lib/postgresql/' '--includedir=/usr/include/postgresql/' '--with-extra-version= (Debian 14~beta3-1.pgdg+1)' '--enable-nls' '--enable-thread-safety' '--enable-tap-tests' '--enable-debug' '--enable-dtrace' '--enable-cassert' '--disable-rpath' '--with-uuid=e2fs' '--with-gnu-ld' '--with-lz4' '--with-pgport=5432' '--with-system-tzdata=/usr/share/zoneinfo' '--with-llvm' 'LLVM_CONFIG=/usr/bin/llvm-config-11' 'CLANG=/usr/bin/clang-11' '--with-systemd' '--with-selinux' 'MKDIR_P=/bin/mkdir -p' 'PROVE=/usr/bin/prove' 'TAR=/bin/tar' 'XSLTPROC=xsltproc --nonet' 'CFLAGS=-g -O2 -fstack-protector-strong -Wformat -Werror=format-security' 'LDFLAGS=-Wl,-z,relro -Wl,-z,now' '--with-gssapi' '--with-ldap' 'build_alias=aarch64-linux-gnu' 'CPPFLAGS=-Wdate-time -D_FORTIFY_SOURCE=2' 'CXXFLAGS=-g -O2 -fstack-protector-strong -Wformat -Werror=format-security' $ find . -name '*jit*.so' ./usr/lib/postgresql/14/lib/llvmjit.so It's certainly expected to work on this arch, and we have snakefly and eelpout testing it in the build farm.
