Hi PostgreSQL developers!
I recently got a rather interesting Debian bug [1]: When upgrading a
pre-8.1 database to 8.1, the upgrade messes up permissions if the old
database had users and groups with the same name. Since in 8.1 they
get collapsed to a 'role' there will be a name clash.
My current solution checks for this situation and aborts the upgrade
if there is at least one name which is both an user and a group (and
asks for renaming either before attempting the upgrade again).
For an upstream solution, maybe pg_dumpall should detect this
situation and abort with an error?
Thank you in advance for any idea,
Martin
