Create table with foreign keys blocked by other Table-level Lock

I'm not pretty sure it is database question or development-process question, but I will kindly give it a try. When creating a new table B with foreign keys to table A, the operation tries to acquires SHARE ROW EXCLUSIVE lock on the referenced table (table A). However if table A is being busy by various UPDATES (ROW EXCLUSIVE locks). This cause my database migration locks for too long time (15+ minutes) and risk my production. In Some occasions I manually assist my db migration by killing the workers directed to table A. Beside scheduling almost *every* db migration to occurs in the off-hours (1AM-5AM), can you suggest a better or creative solution to help my team deploy "*naive*" PR to production.
