Can any one give an example of the difference between a column_alias and a column_definition when
using a function in the FROM clause?
from the manual:
http://www.postgresql.org/docs/8.2/interactive/sql-select.html
"function_name ( [ argument [, ...] ] ) [ AS ] alias [ ( column_alias [, ...] | column_definition
[, ...] ) ]"
