Bug reference: 1244
Logged by: Fernando del Valle
Email address: delsat-sec@data54.com
PostgreSQL version: 8.0 Beta
Operating system: Windows XP
Description: Postgres doesn't work on FAT
Details:
Postgres installs fine on W2K + FAT32, but not on Windows XP + FAT32. The
difference seems to be in CACLS.EXE, which is used by the installer to
change the permissions of files. When used on a file in a FAT32 filesystem,
in Windows 2000, CACLS.EXE returns ok (even though it does not perform the
operation, as it can't). On XP, CACLS.EXE returns an error and the installer
aborts. We have tested it with 7.5 devel and 8.0, and fails with both of
them.
BTW, the link to the bug reporter (this page) is not working (it should
point to /bugform.html and not to /bugs/bugs.php).
