This is hardly surprising, because you have explicitly set up an
infinite loop.

If you wish to change the record being updated or inserted, you should
use a BEFORE trigger, change NEW (the record to be inserted or the
after-update record) and return NEW.

Check the documentation:

PL/pgSQL
Trigger procedures
