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
