Here are other changes included in this pull request:
https://www.postgresql.org/support/versioning/ - 9.1 EOLed on September 2016. - 9.2 EOLed on September 2017. 9.3 is also not supported since Nov 8, 2018. https://www.postgresql.org/about/news/1905/ I think it may be a little bit early to drop PostgreSQL 9.3 yet. * Deprecated `supports_ranges?` since no other databases support range data type * Add `supports_materialized_views?` to abstract adapter Materialized views itself is supported by other databases, other connection adapters may support them * Remove `with_manual_interventions` It was only necessary for PostgreSQL 9.1 or earlier * Drop CI against PostgreSQL 9.2
