Report on IRC:
"I've just installed a new instance of mediawiki. I created a test user called "Test" by registering with that name. Now, I've logged in as the administrator user and I'm trying to block the test user, but the blocking interface says the user is already blocked. However, the block list says there's nobody there, and indeed the user doesn't seem to be blocked in any way. I'm using mediawiki 1.12 and PostgreSQL 8.3, anyone know what might be wrong?"
Sounds like a DBMS issue to me.
Version: 1.12.x
Severity: normal
