Any local user, yes.

Did you recently change the pg_hba.conf file? If so, maybe you forgot
to SIGHUP the postmaster to get it to re-read the file. Otherwise, my
only thought is that you aren't talking to the same postmaster you
thought you were ... that pg_hba.conf should definitely let in any
local connection ...
