v2-0001-Use-pstrdup-for-remote_host-and-remote_port-save-.patch (application/octet-stream) patch v2-0001

I'm glad you are bringing up this issue. By the way, there are two more
annoying places in postmaster.c for pg16 and older. See, strdup() also may
fail if insufficient memory available.

PFA patch for a REL_16_STABLE. It also applies to older versions.
