Is it possible to have a user-defined function (a plpqsql function)

Not according to the documentation:
http://www.postgresql.org/docs/8.2/interactive/sql-createtable.html
DEFAULT default_expr
The DEFAULT clause assigns a default data value for the column
whose column definition it appears within. The value is any
variable-free expression (subqueries and cross-references to other
columns in the current table are not allowed). The data type of the
default expression must match the data type of the column.
The default expression will be used in any insert operation
that does not specify a value for the column. If there is no
default for a column, then the default is null.
