GPDB compatibility fixes:

When connected to a Greenplum database server
- Hide items that not work with GPDB, such as Triggers, FDW, FTS_*, etc
- Tables/Views/Catalogs/Language node can expand correctly
- Views/Languages/Catalogs can show properties dialog with correct information
- Show a greenplum icon at the server node
