Patch to add Postgis adapter support
I've been running Redmine with postgis adapter for while to support a plugin for spatial data.
The proposed patch is necessary to eliminate annoying waning messages from Gemfile and to allow Query with case insentive (ILIKE), since postgis only adds spatial functions on top of the postgresql adapter.
It was tested for several months on FreeBSD 12 and CentOS 7.
Thanks for the opportunity to discuss this subject!
I think it is not going to break builtin compatibility with pg adapter, as stated in https://rubygems.org/gems/activerecord-postgis-adapter :
ActiveRecord connection adapter for PostGIS. It is based on the stock PostgreSQL adapter, and adds built-in support for the spatial extensions provided by PostGIS. It uses the RGeo library to represent spatial data in Ruby.
I read parts of the postgis source code, and it really uses pg adapter to address all non spatial queries.
