Oh, I'm sorry for my strange wording.
I said that the index search collapses to a sequential scan if you do
not
cast the number to int2.
Because an int2 index is not used to look up an int4.
And untyped numbers are int4 or numeric the int2 index is never used
unless
explicitely specified (by a type cast).
Yes this is a known bug in PostgreSQL 7.1 and below. Hopefully this will
get addressed in 7.2?
Why don't I code it? I'm busy working on ecpg (dyn. SQL) at the moment.
