For the seconds, do you want seconds if it's not 00, or do you just not
want seconds at all? Because removing :SS will get rid of the seconds
display.

For the leading 0s, you'd probably need to do a user defined function to
trim them off, but it'd probably be relatively simple use of ltrim, so you
might do something like:

create function format_time(time) returns text as '
 select ltrim(to_char($1, ''HH:MI AM''), ''0'')' language 'sql';
