Hi,
I'm very new to this list -- I've been using and advocating PostgreSQL for
no less than 4 or 5 years now, and have participated in some of the other
mailing lists, but never on this one.
My question is (short version): how would one go about adding a new
(built-in) function to PostgreSQL?
Ask your question as a separate post, not as an answer t another
thread :)
I know... Sorry -- My brain must have temporarily shut down when I was
posting. Wrong subject, wrong link to the rest of the messages... :-(
My "feature request" (which again, I'd like to implement it myself) would
be the ability to do:
select sha1('xyz'), sha256('etc');
(At least these two -- maybe for completeness it would be good to have
sha224, 384, and 512, but I guess SHA1 and SHA-256 would be a very good
and sound starting point)
Take a look at the pgcrypto contrib module (in src/contrib/pgcrypto )
Not only does it show how to add functions, but it also provides many of
the ones you need.
Ok. Will do.
Thanks for the pointer!
Carlos
