Postgresql Schema Incompatibility

The i18nstrings component uses "oid" as a field name in the schema. The name "oid" is reserved in Postgresql, so errors occur when attempting to enable the i18nstrings module.

The problem is easily resolved. The attached patch renames the field to o_id instead; I'm not sure of your naming convention, but it should be simple to search and replace o_id with another name if you prefer.
