Modify array operations to include array's element type OID in the

Browse Source 
array header, and to compute sizing and alignment of array elements
the same way normal tuple access operations do --- viz, using the
tupmacs.h macros att_addlength and att_align.  This makes the world
safe for arrays of cstrings or intervals, and should make it much
easier to write array-type-polymorphic functions; as examples see
the cleanups of array_out and contrib/array_iterator.  By Joe Conway
and Tom Lane.

@@ -41,9 +41,9 @@ attribute equal to a given value or matching a regular expression:
The scheme is quite general, each operator which operates on a base type
can be iterated over the elements of an array. It seem to work well but
defining each new operators requires writing a different C function.
Furthermore in each function there are two hardcoded OIDs which reference
a base type and a procedure. Not very portable. Can anyone suggest a
better and more portable way to do it ?
defining each new operator requires writing a different C function.
This is tedious, and error-prone since one must take care that the correct
datatypes are associated with the selected underlying function.
Can anyone suggest a better and more portable way to do it ?
See also array_iterator.sql for an example on how to use this module.
