Hi,

I'm new to PostgreSQL, but have installed it on a RedHat 6.2 box. We are
currently trying to migrate our existing MySQL applications to PostgreSQL,
but the differences in syntax are presenting a few problems.

My main stumbling block is the apparent lack of a function to form a hash
(or other one-way encrypt) of a password to enter as a field in the
database. The old SQL looks something like:

> INSERT INTO Users (Name, Password) VALUES ('John Smith',
PASSWORD('mypassword'))

This works because "PASSWORD" is an internal function in MySQL. Is there a
similar function in PostgreSQL, or some other way of achieving the same
effect? The data itself is not being moved over, so there is no need for the
same algorithm to be used.

Thanks for any and all help,
