The problem is that youre using to_tsvector('english' for parsing the text but
don't specify the text yearch configuration for the query. The default english
configuration does stemming, the default_text_search_configuration obviously
not.
Try ... to_tsvector('english', post_text) @@ to_tsquery('english', 'europe')
