Try to_char(the_date_you_want_to_display, 'MonthYYYY') for that. Note
that there actually is no need to use date_trunc here as to_char will
only represent only what you ask for anyway. You can find more in the
PostgreSQL Online Manual at http://www.postgresql.org/docs/manuals/
(select the one for the version you are using). The chapter is
'Functions and Operators', section 'Data Type Formatting Functions'.
HTH,
Alex
