Meeting Notes

PostGIS - June 2, 2022

Goals

• Beat PostgreSQL 15 to release!
• Release GEOS 3.11 by mid-early-June
• Release PostGIS 3.3.0beta by end of July (or freeze release beta?)
• Release PostGIS 3.3.0 by end of August

Major Tasks Outstanding

GEOS

• Final CAPI addition for PolygonHullSimplifier
• Change to GEOSTriangulate from GEOSConstrainedDelaunayTriangulation

PostGIS

• ST_ConcaveHull - Add GEOS 3.11 polygon/multipolygon hull functionality (GEOSConcaveHullOfPolygons)
  • need hack to handle linestrings, hack segmentize linestrings)
• Expose GEOS 3.11 GEOSConstrainedDelaunayTriangulation AKA GEOSTriangulate
  • sort out ST_DelaunayTriangles - change to add special case for polygonal? sort out
  • ST_Triangulate - new function
• Expose GEOSPolygonHullSimplifier
  • ST_SimplifyArea - with integer flag for outer/inner (which might get a 3rd option for "neutral" sometime) outer will be default
• Remove patch version upgrades for 3.3+
• Future SFCGAL should be prefixed CGAL_ to pevent namespace clash
• documentation on how to install postgis extensions in non-default schema
• Tiger extension update for tiger 2021 (probably 2022 by release time)
• Our CREATE EXTENSION scripts should be CREATE instead of CREATE OR REPLACE
• ALTER EXTENSION (leave alone for now) since even unchanged, the lib file might have changed (e.g 2.5 to 3.3) (except for net-net new)
