postgres remove foreign key constraint

To remove a foreign key constraint in PostgreSQL using ActionScript, you can use the ALTER TABLE statement with the DROP CONSTRAINT clause. Here's an example:

var sql:String = "ALTER TABLE table_name DROP CONSTRAINT constraint_name;";

Replace table_name with the name of the table that contains the foreign key constraint, and constraint_name with the name of the foreign key constraint you want to remove.

Please note that you need appropriate privileges to execute this operation.
