SHA-1 vs MD5

Hi list,<br /><br />I know that there is a md5 internal function on postgresql, but I noticed that it isn't the more
securetoday. I would like to know if there is a SHA-1 function implemented yet of, if not, if the team has plan to
introduceit on PostgreSQL. <br /><br />Regards ...<br clear="all" /><br />-- <br />Ezequias Rodrigues da Rocha<br /><a
