select *
from table
where id in (3, 2, 5, 1, 4)
order by
case when (id = 3) then 1
when (id = 2) then 2
when (id = 5) then 3
when (id = 1) then 4
when (id = 4) then 5
else null
end
;
could you not use the values statment of psql 8.2 hmmm
select * from table, values ((1,3),(2,2),(3,5),(4,1),(5,4)) as values
where values.id=table.second order by values.first;
never done it but I think it should work with a bit of playing arond...
