Well, this is not an issue actually but fact that postgresql is very strict
about it's data types. You need to cast explicitly even for those types which
'seem' compatible, such as int4 and int2.

Try explain select bid_id, bid_time from bid where bid_id = 10000::bigint

Again try typecasting.
if (select count(*) from bid where bid_id::bigint = in_bid_id::bigint) = 1 then
I doubt in_bid_id needs to be casted that explicitly but I am sure it will be
safe..:-)
