Ah-hah, so your problem is a library mismatch between where you compiled
postgres and where you're trying to run it.

This is not the first time we've had to suggest that people run
"postgres -V" manually to debug a problem. I see that find_other_exec()
intentionally routes the stderr output of that to /dev/null:

snprintf(cmd, sizeof(cmd), "\"%s\" -V 2>%s", retpath, DEVNULL);

It strikes me that this is just a damfool idea. Generally there should
be no stderr output, and if there is some, hiding it from the user is
not helpful. Does anyone object to removing that redirection?
