  • Speep up geometry type reading (J.Santana @ CartoDB)

  • Allow geography columns with SRID other than 4326
  • Small objects getting inappropriately fluffed up w/ boxes
  • Have postgis_typmod_dims return NULL for unconstrained dims
  • Allow duplicate points in JSON, GML, GML ST_GeomFrom* functions
  • Fix ND-GiST picksplit method to split on the best plane
  • Make operators <-> and <#> available for PostgreSQL < 9.1
  • Fix dimensionality confusion in &&& operator
  • Allow unregistering layers of corrupted topologies
  • Avoid exceptions from TopologySummary
