Yeah, bt should work anyway, though you won't get details about functions
for which the corresponding "debug symbols" package isn't installed.
The above is showing that you lack debug symbols for glibc, but it's
unlikely that that is going to be of interest here. What *is* of interest
is Postgres proper and the relevant FDW, so make sure that those symbols
are installed. (At least on Red Hat-based systems, gdb will tell you
which debug symbol packages you're missing when you first attach to
a process or core file.)
