Andreas Schild who provided many corrections to core docs.
PostGIS Japanese translation team first to reach completion of translation.
- Support for PostgreSQL 10
- Preliminary support for PostgreSQL 11
- #3645, Avoid loading logically deleted records from shapefiles
- #3747, Add zip4 and address_alphanumeric as attributes
to norm_addy tiger_geocoder type.
- #3748, address_standardizer lookup tables update
so pagc_normalize_address better standardizes abbreviations
- #3647, better handling of noding in ST_Node using GEOSNode
(Wouter Geraedts)
- #3684, Update to EPSG register v9
(Even Rouault)
- #3830, Fix initialization of incompatible type (>=9.6) address_standardizer
- #3662, Make shp2pgsql work in debug mode by sending debug to stderr
- #3405, Fixed memory leak in lwgeom_to_points
- #3832, Support wide integer fields as int8 in shp2pgsql
- #3841, Deterministic sorting support for empty geometries in btree geography
- #3844, Make = operator a strict equality test, and < > to rough "spatial sorting"
- #3855, ST_AsTWKB memory and speed improvements
* Breaking Changes *
- Dropped support for PostgreSQL 9.2.
- #3810, GEOS 3.4.0 or above minimum required to compile
- Most aggregates now marked as parallel safe,
which means most aggs have to be dropped / recreated.
If you have views that utilize PostGIS aggs,
you'll need to drop before upgrade and recreate after upgrade
- #3578, ST_NumInteriorRings(POLYGON EMPTY) now returns 0 instead of NULL
- _ST_DumpPoints removed, was no longer needed after PostGIS 2.1.0
when ST_DumpPoints got reimplemented in C
- B-Tree index operators < = > changed to provide better spatial locality on sorting
and have expected behavior on GROUP BY.
If you have btree index for geometry or geography, you need to REINDEX it, or review
if it was created by accident and needs to be replaced with GiST index.
If your code relies on old left-to-right box compare ordering,
update it to use << >> operators
PostGIS 2.4.0rc3
2017/09/27
* Fixes and Enhancements since PostGIS 2.4.0rc2 *
- #3781 st_contains cannot handle curvepolygon / compoundcurve
consisting of only straight lines
- #3866 server crashing from large values in ST_AsTWKB
- #3818 Allow triangles unclosed in M to be WKT parsed
- several packaging changes regarding checking trailing blanks
PostGIS 2.4.0rc2
2017/09/24
* Fixes and Enhancements since PostGIS 2.4.0rc1 *
- Numerous fixes to ST_AsMVT, ST_AsGeoBuf
- ST_AsTWKB speed and memory performance enhancments
- ST_RepeatedPoints speed improvements
- ST_ConcaveHull bug fix
See PostGIS 2.4.0 section for details of
new features and enhancements in this release.
PostGIS 2.4.0rc1
2017/09/13
Note possible breaking changes since 2.4.0 beta1 release are:
* Breaking Changes *
- B-Tree index operators < = > changed to provide better spatial locality on sorting
and have expected behavior on GROUP BY.
If you have btree index for geometry or geography, you need to REINDEX it, or review
if it was created by accident and needs to be replaced with GiST index.
If your code relies on old left-to-right box compare ordering,
update it to use << >> operators.
- ST_AsMVT aggregate now overloaded and arg order changed.
Check your code if you are already using this function.
- _ST_DumpPoints removed, was no longer needed after PostGIS 2.1.0
when ST_DumpPoints got reimplemented in C
Upstream has very complicated ifdefs that try to define UNIX
everywhere but windows, except that it fails to include NetBSD. Then,
it uses UNIX to avoid using the non-standard stricmp and instead use
the POSIX-conforming strcasecmp.
For pkgsrc, rip out an entire screenful of complexity and just define
UNIX if not defined. Resolves build on NetBSD 7, and probably other places.
Drop build patch incorporated upstream.

Disable address standardizer, which seems to build if some of what it
requires (pcre) happens to be installed, until I figure out if it should
be built and require the dependencies.
Add patches (already reported upstream) to work around upstream using
PERL from pgxs, which is "missing" in pkgsrc, because the
postgresql-client build didn't require perl, and to use @PERL@, found
by postgis configure instead.
Passes tests on NetBSD-6 i386 with postgresql93.

PostGIS adds support for geographic objects to the PostgreSQL object-relational
database. In effect, PostGIS "spatially enables" the PostgreSQL server,
allowing it to be used as a backend spatial database for geographic information
systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS
follows the OpenGIS "Simple Features Specification for SQL" and has been
certified as compliant with the "Types and Functions" profile.
PostGIS/PostgreSQL includes the following functionality:
* Simple Features as defined by the OpenGIS Consortium (OGC)
* Support for Well-Known Text and Well-Known Binary representations of GIS
objects
* Fast spatial indexing using GiST
* Geospatial analysis functions
* PostgreSQL JDBC extension objects corresponding to the geometries
* Support for OGC access functions as defined by the Simple Features
Specification
This is postgis 2.x, the currently-maintained and recommended version.
