问题是在执行Ansible的数据操作过程中出现SQLParseError错误，错误信息提示“PostgreSQL不支持表名中超过三个点号”的情况。解决方法是修改Ansible的源代码，将该错误信息捕获，并通过自定义函数替换掉表名中的多个点号。代码示例如下：

1. 修改Ansible源代码中的pgsql.py文件，捕获SQLParseError错误：

try: result = cursor.execute(sql, args) except psycopg2.Error as exc: if isinstance(exc, psycopg2.ProgrammingError) and 'relation' in str(exc): raise self._rel_does_not_exist(exc, statement) elif isinstance(exc, psycopg2.InternalError) and 'does not support' in str(exc): exc_message = str(exc) if "table with more than 3 dots" in exc_message: exc_message = exc_message.replace("table with more than 3 dots", "table with multiple dots") exc = psycopg2.InternalError(exc_message) raise self._translate_exception(exc, statement)

2. 定义自定义函数replace_dots，在处理表名时将多个点号替换为单个点号：

def replace_dots(identifier): return re.sub(r'.{2,}', '.', identifier)

3. 在ansible/modules/database/postgresql/pg_user.py等文件中调用自定义函数，实现表名中多个点号的替换：

def _get_table_column_priv(self, table): # parse table name, handle when table name contains schema if '.' in table: schema, table = table.split('.') schema = replace_dots(schema) table = replace_dots(table) else: schema = 'public'

    # get privileges for columns of the table
    query = self.owner_user_query("SELECT attname, format_type(atttypid, atttypmod)"
                                   " FROM pg_attribute WHERE attrelid ="
                                   " (SELECT oid FROM pg_class c JOIN pg_namespace n"
                                   " ON n.oid=c.relnamespace WHERE n.nspname = %s AND relname = %s)"
                                   " AND NOT attisdropped", (schema, table))
