You use the chkpass type that I just commited to the distribution (finally.)
Here is an example of its usage.
darcy=# CREATE TABLE x (i serial, p chkpass);
NOTICE: CREATE TABLE will create implicit sequence 'x_i_seq' for SERIAL column 'x.i'
NOTICE: CREATE TABLE/UNIQUE will create implicit index 'x_i_key' for table 'x'
CREATE
darcy=# INSERT INTO x (p) VALUES ('hello');
INSERT 805247 1
darcy=# INSERT INTO x (p) VALUES ('goodbye');
INSERT 805248 1
darcy=# SELECT * FROM x;i | p
---+----------------1 | :SoLA2YFpQYV/I2 | :Sg8CKkFqqTGec
(2 rows)
darcy=# SELECT p = 'hello' FROM x WHERE i = 1;?column?
----------t
(1 row)
darcy=# SELECT p = 'hello' FROM x WHERE i = 2;?column?
----------f
(1 row)
darcy=# SELECT i, raw(p) FROM x;i | raw
---+---------------1 | SoLA2YFpQYV/I2 | Sg8CKkFqqTGec
(2 rows)

Does that mean that chkpass is part of 7.1, or only the current CVS?

Unless someone rips it out again, it will be part of 7.1.1.
I think D'Arcy acted inappropriately in committing a new-feature item
before we'd made the branch for 7.2 development. But I don't have the
time to argue about it...

I usually do the encrypting in the client application (AOLserver, PHP), store the encrypted password, when the user comes back and enters the password I encrypt it and test it against what's on the database. -Roberto -- +----| http://fslc.usu.edu USU Free Software & GNU/Linux Club |------+ Roberto Mello - Computer Science, USU - http://www.brasileiro.net http://www.sdl.usu.edu - Space Dynamics Lab, Developer Thou shall not kill, unless it's for dinner!
i could not find chkpass in pgsql datatypes ...
it is giving error called :
Unable to locate type name chkpass in catalog.
what shall i do ??

You need the code that I just committed. You can get the files from http://www.ca.postgresql.org/cgi/cvsweb.cgi/pgsql/contrib/chkpass/. -- D'Arcy J.M.
