PGDATA is built from `pwd`, so it breaks if the build directory has a
space in it. Because it's testing for the absence of files, it doesn't
actually break the test, but would fail to detect the bugs it's trying
to.
+ find /home/ilmari/src/post gresql/src/bin/pg_upgrade/tmp_check/data -type f !
-perm 640
+ wc -l
find: ‘/home/ilmari/src/post’: No such file or directory
find: ‘gresql/src/bin/pg_upgrade/tmp_check/data’: No such file or directory
+ [ 0 -ne 0 ]
+ find /home/ilmari/src/post gresql/src/bin/pg_upgrade/tmp_check/data -type d !
-perm 750
+ wc -l
find: ‘/home/ilmari/src/post’: No such file or directory
find: ‘gresql/src/bin/pg_upgrade/tmp_check/data’: No such file or directory
+ [ 0 -ne 0 ]
Attached is a patch fixing this. I checked the rest of the script, and
this seems to be the only place lacking quoting.
