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/i...ql-select.html

"function_name ( [ argument [, ...] ] ) [ AS ] alias [ ( column_alias [, ...] | column_definition
[, ...] ) ]"
