password in pg_shadow - Mailing list pgsql-hackers

Is all in next example good? See:

abil=> CREATE USER myname WITH PASSWORD BuBuBuBu;
CREATE USER                            ^^^^^^^^^^ 

abil=> select * from pg_shadow;
usename |usesysid|usecreatedb|usetrace|usesuper|usecatupd|passwd     |valuntil
myname  |    5808|f          |f       |f       |f        |bubububu   |
      ^^^^^^^^

Why is in pg_shadow.passwd low case only?
