Reference notes for transforming Accra / Ghana National Grid geometry to WGS 84
in PostGIS: ST_Transform, ST_SetSRID for columns reporting SRID 0, updating a
column in place, and altering a column whose type modifier locks it to 2136.
Relevant wherever data arrives on the national grid while the API and the
application work in 4326 throughout.
