 Priority:  medium              |  Milestone:  PostGIS 2.5.0
Component:  postgis             |    Version:  2.4.x

 SYNOPSIS
 The documentation states the following:

 ```
 What is the longest arc you can process?
 We use great circle arcs as the "interpolation line" between two points.
 That means any two points are actually joined up two ways, depending on
 which direction you travel along the great circle. All our code assumes
 that the points are joined by the *shorter* of the two paths along the
 great circle. As a consequence, shapes that have arcs of more than 180
 degrees will not be correctly modelled.
 ```

 This is an issue when users want to create larger features, or, maybe even
 more importantly, when an envelope is passed which is greater than this
 limit (i.e. displaying all capital cities in the world, which uses a
 spatial envelop, will return incorrect results).

 SQL Server used to have this limitation as well; however, as of SQL Server
 2008, they provided a solution that eliminates this limitation.

 I wanted to put in a request for an enhancement to resolve this issue.

 Thank you for your consideration.
