Add this line to the top of your dump file:
SET FOREIGN_KEY_CHECKS = 0;
And this line to the bottom:
SET FOREIGN_KEY_CHECKS = 1;
There should be some checkboxes in PMA that deal with foreign key constraints. If not, then this is a PMA bug. Incidentally, this is why I never used postgresql, by default it didn’t come with any tools to dump and restore tables with Fkeys, it always got the order wrong.
