/**
 * Testcase for creating postgis-based resources on geoserver.
 * <P>
 * Since these tests require a running postgis instance, this is more like integration tests.<br/>
 * You may skip them by defining<tt> <pre>
 *        -DpgIgnore=true </pre></tt>
 * When <tt>pgIgnore</tt> is defined that way, failing tests will not break
 * the build: they will be logged as errors instead.
 *
 * <P>
 * The target postgis instance can be customized by defining the following env vars: <ul>
 * <LI><TT>pgHost</TT> (default <TT>localhost</TT>)</LI>
 * <LI><TT>pgPort</TT> (default: <TT>5432</TT>)</LI>
 * <LI><TT>pgDatabase</TT> (default: <TT>test</TT>)</LI>
 * <LI><TT>pgSchema</TT> (default: <TT>public</TT>)</LI>
 * <LI><TT>pgUser</TT> (default: <TT>utest</TT>)</LI>
 * <LI><TT>pgPassword</TT> (default: <TT>ptest</TT>)</LI>
