A school I work with called me with the following problem. they
could not add a grant for a particular user. they got a message
about not finding column GRANT. I had them dump and reload the
database and they got the following error on restoring. Their
database runs on Linux. I got a copy of their database and did the
same thing with the same error in WinXP. I validated the database no
errors. Has anybody seen this before? Any Ideas?
