----------------------------------------------------------------
Added an initial commit for 9.0 that will backport cleanly. The functions added are:
ST_SIMPLIFY
ST_FORCE_2D (currently just a dummy function)
ST_ENVELOPE
ST_WITHIN
ST_DWITHIN
ST_EXTENT (aggregate function)
ST_HASARC (currently just a dummy function)
&& (operator that we only support with geometry arguments)
ST_GEOMFROMEWKT
ST_ASEWKB
ST_GEOMFROMEWKB
To run with Geoserver you can setup a postgis instance - http://docs.geoserver.org/stable/en/user/gettingstarted/postgis-quickstart/index.html
The instructions are a little out of date, you may just use psql to add the postgis extensions - http://postgis.net/docs/postgis_installation.html
Run Teiid and add that postgresl/postgis instance as a source:
For example in embedded:
ModelMetaData mmd = new ModelMetaData();
mmd.setName("public");
mmd.setModelType(Model.Type.PHYSICAL);
mmd.addSourceMapping("pg", "pg", "pg");
mmd.addProperty("importer.useQualifiedName", "false");
mmd.addProperty("importer.schemaPattern", "public");
mmd.addProperty("importer.excludeTables", "geometry_columns");
es.deployVDB("nyc", mmd);
Note that useQualifiedNames is off and we specifically exclude geometry_columns from the source - this is because Geoserver makes unqualified queries that reference geometry_columns and we need it to resolve against our system table, rather that being ambiguous. You'll also need the pg/ODBC transport to be enabled:
EmbeddedConfiguration ec = new EmbeddedConfiguration();
SocketConfiguration sc = new SocketConfiguration();
sc.setProtocol(WireProtocol.pg);
sc.setPortNumber(5433);
ec.addTransport(sc);
Also org.teiid.backslashDefaultMatchEscape must be set to true as geoserver will issue pg (non-ansi) queries with like predicates assuming \ as the escape.
>From there just follow the instructions from the rest of http://docs.geoserver.org/stable/en/user/gettingstarted/postgis-quickstart/index.html but point it to the Teiid port instead of postgresl.
