As I understand the issue in autoslave.install file. There is 'ts' field (looks like short from timestump), the field type is 'datetime'. For PostgreSQL it's not fully correct. I had change it to 'int' type, set 'not null' => true and 'default' => 0.
Notice, install file has two such fields in schema function, both have to change. After that installation runs over.
