I think I have found out something suspicious.
I used tcpdump to monitor the traffic to and from port 5432, and it
seems that the password the client on A sends out to the postmaster on B
is
"md54570471eccef21ae3c6e43033d8d2f66"
While the MD5-ed password stored in system catalog (pg_shadow) is
"md5c573460a3b356e4610bfae406e1d8a9f"
And a MD5 string generated by md5 function in postgresql is:
template1=# select md5('test_passwd');
md5
----------------------------------
daac2bc8c6fe94375b59efb7b3effd33
(1 row)
(As you can see, all 3 strings are different)
Why the difference? Is there something missing ??
Thanks
