Revision history for DBIO-PostgreSQL-PostGIS

0.900000  2026-06-23
    First release. PostGIS spatial extension support layered on DBIO::PostgreSQL.

    * Result component
        - load_components('PostgreSQL::PostGIS') auto-inflates geometry and
          geography columns to DBIO::PostgreSQL::PostGIS::Geometry objects and
          deflates them back to EWKT on write
        - column metadata carries geometry_type and srid; auto-detection
          overridable via inflate_geometry on the column
        - promotes the result source's resultset_class to the PostGIS
          ResultSet on first spatial column, leaving custom subclasses alone

    * Geometry value object
        - constructors: point, linestring, polygon, bbox_polygon, from_wkt,
          from_ewkt, from_ewkb_hex, from_geojson, from_lat_lon
        - accessors: srid, geometry_type, wkt, ewkt, ewkb_hex, x, y, z,
          coordinates, bbox, is_empty, to_geojson
        - lazy WKT/WKB parsing delegated to the codec chain

    * Codecs
        - WKT/EWKT parser and builder
        - EWKB-hex decoder with bounds checking

    * Spatial ResultSet helpers
        - within_distance, nearest_to, order_by_distance, with_distance
        - bbox_intersects (&&), KNN ordering (<->)
        - predicates: intersects, contains, within, touches, crosses, overlaps

    * Storage, Introspection and Deploy
        - Storage: ensure_postgis, postgis_version
        - Introspect: augments geometry/geography columns by parsing
          data_type (e.g. geometry(Point,4326)) into geometry_type and srid
        - Deploy: PostGIS-aware introspection for diff/install round-trips
