EDB Postgres Advanced Server 18.3.0 release notes v18
Released: 26 Feb 2026
Why is RHEL 9.6 not supported for EPAS 18?
- Version pivot: Due to OpenSSL and LLVM breakages introduced in RHEL 9.7, our current minor releases for back-branches for version 17 and earlier were built on RHEL 9.6 to maintain stability for existing users.
- EPAS 18 requirement: Moving forward, EPAS 18 is specifically designed for RHEL 9.7 and later versions. It relies on the newer toolset available in 9.7, which is incompatible with the 9.6 environment.
