Hi Sarah, I am not sure what you mean by "there"? I already have a fix for this bug here, which is the patch I linked in comment 29 that applies unchanged to PostgreSQL 13 and can easily be backported to versions 12 and 11. Older versions have no support for LLVM. As for the LLVM13 fix that upstream made in the latest PostgreSQL releases, that one does not seem to be specific for s390x, and this upstream commit seems to be a good starting point for further investigation: https://github.com/postgres/postgres/commit/d9c05a9ec49399a45d30acacac748625922cbe40
