我有一个架构public和数据库schema_A.我需要创建一个schema_b结构相同的新模式schema_a.我发现下面的函数,问题是它不复制外键约束.

CREATE OR REPLACE FUNCTION clone_schema(source_schema text, dest_schema text)
  RETURNS void AS
$BODY$
DECLARE
  object text;
  buffer text;
  default_ text;
  column_ text;
BEGIN
  EXECUTE 'CREATE SCHEMA ' || dest_schema ;

  -- TODO: Find a way to make this sequence's owner is the correct table.
  FOR object IN
    SELECT sequence_name::text FROM information_schema.SEQUENCES WHERE sequence_schema = source_schema
  LOOP
    EXECUTE 'CREATE SEQUENCE ' || dest_schema || '.' || object;
  END LOOP;

  FOR object IN
    SELECT …

我有一个转储，其中数据和结构位于公共模式中。我想将其恢复到具有自定义名称的架构中 - 我该怎么做？
