 hi,

I am a little confused on how md5 passwd hashes stored and used in PG. There was a discussion on this issue but it was
moreconfusing for me. When I create a new user its passwd is stored as md5 hashes (I don't know if it related to
hba_confmd5 line, is it??). My hba_conf requires md5 for all connections. And I can connect. Then I change a user's
passwdby UPDATE pg_shadow set passwd blablabla SQL command to for example 'qwerty' without md5 hashing. Then I see the
passwdin pg_shadow as clear text not md5. But I can still connect by using qwerty and md5 connection. Here I am
confused.When I use update ... is it stored as clear-text. If so, when I connect it with md5, is on the wire still md5.
Ifso how PG tells clear-text from md5 on the server side?
