rlm_perl hashes

Hello All If i remove SQL module in default (site enable) in any section then "%RAD_CHECK" hashes is still available in rlm_perl ? In my plan i need to transfer all policy mechanism to my database (PostgreSQL) function but we have some limitation in xlat , so i need to pass all value pairs from request to SQL function and get all reply value pairs in function return . in this case my function read all check value pairs directly from database so i think no need SQL module any more ... So can i transfer all SQL module Task to SQL function in my database ? Best regards.
