PASSWORD vs. md5('somepass')
Hi,
I look for a way to reproduce the encrypted string stored as a password by means other than using the CREATE ROLE command.
When using CREATE ROLE........PASSWORD 'somepass' the resulting string for rolpassword in pg_authid always starts with md5, suggesting it would create some md5 string. So I thought to use SELECT md5('somepass') to get the same.
But the two strings differ. Is there a function that does that outside the create role context?
Thanks
Alex

See pg_authid's explanation of the rolpassword column:
http://www.postgresql.org/docs/9.1/static/catalog-pg-authid.html
which you can reproduce via:
SELECT 'md5' || MD5(role_password_here || role_name_here);
