Description (last modified by Hannes Ljungberg)

A couple of full text search related to headlines tests break on the latest PostgresSQL versions (9.6.18, 10.13 11.8, 12.3). The reason appears to be that a trailing ! is now present in the results which breaks the equality checks. Looking at the 10.13 release notes (​https://www.postgresql.org/docs/release/10.13/) it's probable that the patch "Fix ts_headline() to make better headline selections when working with phrase queries" introduced this behaviour.
