automatic indices not showing (win32/rev7358)

When I create a table with a PK, and get a notice of the form:

NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "(table)
_pkey" for table "(table)"

Indeed, the index it mentions shows up in pg_index.  pgAdmin, however,
shows zero indices under the table, even after refreshing the table or
even restarting the program.  Is this supposed to be this way?
