Changes since PostGIS 3.0.0alpha1 release are as follows:
- 4404, Fix selectivity issue with support functions (Paul Ramsey)
- 4311, Make wagyu the default option to validate polygons.
This option requires a C++11 compiler and will use CXXFLAGS (not CFLAGS).
It only enabled if built with MVT support (protobuf) and should speed up mvt tile generations
--without-wagyuto disable this option and keep the behaviour from 2.5 (Raúl Marín)
- 4198, Add ST_ConstrainedDelaunayTriangles SFCGAL function (Darafei Praliaskouski)
Note that a major change in 3.0 is that the raster functionality has been broken out as a separate extension. If you are upgrading from a previous edition, do the following:
After installing the binaries or after running pg_upgrade, make sure to do:
1ALTER EXTENSION postgis UPDATE; 2-- this next step repackages raster in its own extension 3-- and upgrades all your other related postgis extension 4SELECT PostGIS_Extensions_Upgrade(); 5 6--if you don't use raster, you can do 7DROP EXTENSION postgis_raster;
