PostgreSQL: integer in statement vs. text column

Created by: snai

I am using stable Gitlab 3.0.3 (commit e469084ccca0d976b0dc069aa89e60a41f067837)

I succesfully created a Issue, and after clicking on it I get a Error 500.

I am on Freebsd 9 x64 pgsql version 9.1.6

I read a lot about this error with postgres, but all of the Issues stated, that this error is resolved.
