When a
user's password in the "<filename>pg_shadow</filename>"
table is NULL, user
authentication proceeds as it historically has (HBA,
PG_PASSWORD, etc). However, if a password is set for a
user, a new authentication system supplants any other
configured for the <productname>Postgres</productname> instance, and the password
stored in the "<filename>pg_shadow</filename>" table is used
for authentication.
For more details on how this authentication system
functions see pg_crypt(3). If the WITH PASSWORD clause is
omitted, the user's password is set to the empty
string with equates to a NULL value in the authentication
