That's a question for Devrim ?

Can you tell which glibc headers were installed when compiling this package?
postgresql11-server-11.5-1PGDG.rhel6.x86_64

I can tell it was compiled using
version | PostgreSQL 11.5 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23), 64-bit

Maybe it doesn't matter, since, for better or worse, is not a "late model" cc.
