PG_RETURN_?



Hi,

I have a set of functions for a data type that return
small integers (i.e. [0..12]).  I can, of course, represent
it as a char, short or long (CHAR, INT16 or INT32).
re there any advantages/drawbacks to chosing one particular
PG_RETURN_ type over another (realizing that they are
effectively just casts)?

Thanks!
