Given:
CREATE DOMAIN int_array AS int[];
The operator [] works fine in 4.1beta1:
SELECT (ARRAY[1,2,3]::int_array)[1];
proving that int_array is an array type with element type int.
It is inconsistent that other array functions and operators don't work.

The documentation for the Server Programming Interface
is underspecified such that it is impossible to create
real extensions using only the documented interface.
For example, in the example 43.5

a variable of type SPITupleTable is
by then, but we'll see!
PostgreSQL is a great tool and y'all are doing great work in maintaining
and improving it. The community has also been very helpful since I got
over my shyness about asking for help.

Dear PostgreSQL Hackers,
Through PostgreSQL 8.3, both of the following functions worked, using
generate_series(array_lower($1, 1), array_upper($1, 1)) i
instead of generate_subscripts($1, 1).
With PostgreSQL 8.4, both are accepted, but only the second one works,
regardless of whether I use
most of what I see in 8.4,

Hi Josh,
I think that any special features common to all on system tables would
go nicely near the top of 44.1 System Catalogs Overview. That plus a
specific error message, not just a PERMISSION DENIED, so that someone
like me can put the error message in the PostgreSQL.org search box to
