Hi Joao,

Just like 'nodes' & 'children' operation, You have to implement several
other methods,

*'obj'* - To create, update, delete & properties for External Tables
Ref: ../foreign_tables/__init__.py: 193
Which will call associated methods, def create(..), def update(...), def
delete(...) & def properties(...)

*'sql'* - Displays reversed engineered sql on SQL panel
Which will call to method def sql(...) method

*'msql'* - Displays reversed engineered sql on Create/Properties dialog
Which will call to method def msql(...) method

*'stats'* -Displays object statistics sql on Statistics panel
Which will call to method def statistics(...) method

*'dependency'* - Displays object dependencies on Dependencies panel
Which will call to method def dependencies(...) method

*'dependent'* - Displays object dependents on SQL panel
Which will call to method def dependents(...) method

Hope that helps.
