Changing auth type in pg_hba.conf ineffective. Why?

I'm struggling to resolve a login error.  It seems that I'm getting
"ident" authentication, no mater what I set pg_hba.conf to.  Here's a
log file:
 LOG:  next transaction ID: 602; next OID: 17232 LOG:  database system is ready    ... FATAL:  Ident authentication
failedfor user "bryce" LOG:  could not connect to Ident server at address "::1", port 113:
 
Connection refused

This makes sense, because no identd is running, and port 113 is blocked
anyway.  So I need another auth method.
My relevant pg_hba.conf lines are:
 #local   all         all                               ident sameuser #host    all         all         127.0.0.1/32
     ident sameuser #host    all         all         ::1/128               ident sameuser local   all         all
                       md5 host    all         all         127.0.0.1/32            trust host    all         all
::1/128               md5
 

I've renamed pg_hba.conf temporarily, just to verify that postmaster
won't start without it.  So I'm editing the right file, and restarting
postmaster correctly.  Any clues why I'm still getting 'auth' method
authentication?
