h1. HowTo make Wiki history working with Postgres 9.0 h2. Problem When accessing the history version of a Wiki page (e.g. Wiki?version=16), just a string which is not human readable is displayed. It starts like this and is about 5000 characters long: <pre> \x68312e204d532050726f63657373696e6720506970656 ... </pre> Same result for exporting TXT or HTML of the current version, and a Wiki-diff just diffs between two such strings. h2. Solution PostgreSQL 9 introduced a new 'hex' format for bytea data input and output. Default for output is now hex, but it can be easily reverted to the old 'escape' format with the following command: <pre> ALTER DATABASE redmine SET bytea_output TO 'escape'; </pre> See also #7677.
