It's (practically) impossible to decrypt a MD5 hashed password. > Or at least, how to transfer value from text-box (MS Access) to Postgres > so that Postgres can determine whether those two values > are the same ? You need to MD5 hash the input passsword and compare hashed input password with the one in pg_shadow. For instance: -- $1 for password input. SELECT usernm FROM recs WHERE passwd = md5($1) Furthermore, it'll bring some potential security problems to be able to access pg_shadow which requires db admin permissions.
