Hi! I've got this update query: http://pastebin.com/m2e29990 Can anyone tell me, how this is possible? If we insert 12 on the end, then it decreases, but 11 remains the same. The problem only occurs, when the where condition contains "sorrend > 9" or less. It occured using "PostgreSQL 8.3.3, compiled by Visual C++ build 1400" and "PostgreSQL 8.3.7 on i486-pc-linux-gnu, compiled by GCC gcc-4.3.real (Debian 4.3.2-1.1) 4.3.2" too.
