maxValue errors

For several operations I get an errormessage. For example when I try to copy a dbfield of a catalog, or try to create a number field. The errors are SQL messages always starting at "maxValue ....". To deal with the problem for now I renamed the maxValue field to mxValue in the database (which already got rid of the message), and I changed every appearance in the PHP code to mxValue. This patched the problem.

It seems MAXVALUE is a reserved word for MySQL:
MAXVALUE is used to represent the least upper bound for the type of integer in question. -MAXVALUE represents the greatest lower bound.

Several users have reported this issue on the German board. Me too. The developers of the catalog extension are aware of this issue. However, they have not yet found what exactly is causing this problem. I will point the devs/users to this thread. Thx.
