Further investigation has shown that the exit/trap idiom used in
pg_regress.sh is less than 100% portable.

The following shell script has been seen to produce incorrect output
on both Cygwin and FreeBSD:


#!/bin/sh

trap '
 st=$?
 echo status = $st
 exit $st
' 0

(exit 9); exit



I seem to recall that there is a bug in the FreeBSD shell with line breaks in traps. Try changing the above to


trap 'st=$?; echo status = $st; exit $st' 0




Thankyou Peter! I'd never have guessed something so obscure!

I have confirmed that this is the problem, and ascertained that the Cygwin shell exhibits the same behaviour.

I will submit a patch for pg_regress.sh shortly (after a little testing using buildfarm).

cheers
