} Use contrib/pgcrypto, store the hashed version of the password (say,
} using SHA1). When you want to check if the correct password is used,
} hash the string the user entered and compare it to the stored version.

Where is the documentation on this? Is it like what I wound up doing (see
below)?

Since I was coming from MySQL, I wanted the PASSWORD() function it has
builtin and I wound up writing it as a C function:

CREATE FUNCTION PASSWORD (text) RETURNS text
AS '/home/gss/src/crypt.so'
LANGUAGE C WITH (isstrict);

I can attach the C source if anyone is interested.
