function
Hi Luke,
I've just been playing with this myself (as you've seen). I'm no
expert...
ME EITHER.
so maybe somebody else can jump in if what I say is incorrect.
DITTO.

As far as I know there aren't any similar functions available in
PostgreSQL. I HAVEN'T FOUND ANY EITHER.
Additionally, I don't see anything wrong with sticking that
logic on the application-side rather than in the database.
FAIR ENOUGH.
Of course, if you do your access-control on the application side, then
you're vulnerable to faults in your PHP code potentially causing
complete database compromise. YEP

One of the reasons we've moved from MySQL to PostgreSQL was to provide
more stringent security by using views and schemas. We decided that the
safest method was to create real users in the PostgreSQL system user
table, and then let Postgres worry about authenticating users. Then,
even if your PHP code is flawed, the SQL commands still execute with
only the users permissions.
INTERESTING
This doesn't solve your original problem though. You still end up
needing to do the md5 hashing in the application layer. I'm curious to
know why you're opposed to this?
NOT EXACTLY OPPOSED -> JUST WANT TO KEEP IT SIMPLE. THE LESS CODE TO
MAINTAIN -> THE BETTER. WOULD RATHER RELY ON DATABASE SYSTEM TO PERFORM
ENCRYPTION TECHNIQUE IF POSSIBLE..
I'm keen to hear other peoples views on the cleanest way to authenticate
users...
ME TOO. THERE'S A LIMITED AMOUNT OF QUALITY INFORMATION ON USING PHP WITH
POSTGRESQL OUT THERE..
Cheers
PEACE
Matthew.
