public class PgServer extends PgAbstractStatement implements PgForeignOptionContainer
PostgreSQL foreign server implementation. Foreign servers define connection information for external data sources that can be accessed through foreign data wrappers (FDWs).

      public ObjectState appendAlterSQL(IStatement newCondition, SQLScript script)
      Description copied from interface: IStatement
      Fill script with object changes and return change type
      Specified by:
      appendAlterSQL in interface IStatement
      Parameters:
      newCondition - new object state
      script - script to collect changes
      Returns:
      object change type

    • getAlterHeader

      public String getAlterHeader()
      Description copied from interface: PgForeignOptionContainer
      Returns the ALTER statement header for this object.
      Specified by:
      getAlterHeader in interface PgForeignOptionContainer
      Returns:
      ALTER statement prefix (e.g., "ALTER FOREIGN TABLE table_name")

      public String getFdw()
      Gets the foreign data wrapper name for this server.
      Returns:
      FDW name

    • setFdw

      public void setFdw(String fdw)

    • getOptions

      public Map<String,String> getOptions()
