Redefining a function that is defined in POSIX and present on most
systems seems like a bad idea. Not in the least because ELF linking
rules mean that if any library (say libssl) in the backend calls qsort,
they'll get the postgresql one, rather than the C library like they
expect. That seems fragile to me.

The #define would be fine, as long as you make sure it's called after
the system headers, otherwise the problem isn't fixed.

Have a nice day,
