PostgreSQL version: 8.2
Operating system: FreeBSD
Description: Can't rollup array of arrays
Details:

Dunno about the spec, but I would think this should work:

tinman(at)localhost/tinman[]=# SELECT array(select array[table_name,
column_name] FROM information_schema.columns LIMIT 10);
ERROR: could not find array type for datatype character varying[]

tinman(at)localhost/tinman[]=# SELECT version();
version

----------------------------------------------------------------------------
--------------------
PostgreSQL 8.2.4 on i386-portbld-freebsd6.2, compiled by GCC cc (GCC) 3.4.6
[FreeBSD] 20060305
(1 row)

The expectation is the production of an array like:
'{{table_foo,column_bar},{table_foo,column_bar2},...}'.

No? (yeah, it may be more of a feature request than a bug)
