pgsql: Remove inappropriate raw_expression_tree_walker() code

Remove inappropriate raw_expression_tree_walker() code

It was walking into the ColumnDef->compression field, which is not a
node but a string.  This code is currently not reachable (because the
compression field is only set in situations that don't go through
raw_expression_tree_walker()), but if it had been, this could have
behaved erratically.
