This'll hopefully change. This bypasses the writers used in JDBCFeatureStore, as I'm just not yet confident in them. We also should do some solid tests to see which is actually faster.<P><P><DL><DT><B>Author:</B></DT> <DD>Chris Holmes, TOPP</DD><DT><B>Module:</B></DT><DD><CODE><B>plugin/postgis</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-postgis/"><CODE>gt2-postgis.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/postgis/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/plugin/postgis/src/org/geotools/data/postgis/PostgisFeatureStore.java">SVN head</A>)</DD><DT><B>'TODO:'</B></DT> <DD>HACK: too little code reuse with PostgisDataStore., TODO: make individual operations truly atomic.
