somethingto do with NLS, but I'm confused about what I need to do to get an extension to work. The documentation in
chapter57 of the user's manual seems to address stand-alone programs. At least that is my understanding.

That seems really weird. You wouldn't think that an NLS problem could
cause an invalid ELF header.
If I were trying to troubleshoot this, I'd set up the failing scenario
(i.e. lc_messages=pt_BR.utf8), set a breakpoint in the server on
errstart, and then perform the failing action. Then I'd use gdb to get
a backtrace from the point where the error was thrown, and hope that
the contents of that backtrace made it more clear what was actually
happening.
