[Koha-devel] borrower_message_preference_id reaches limit - quickfix?

Kia ora and happy new year, Koha! Yesterday I reported this bug: Bug 32556 - borrower_message_preference_id reaches limit https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32556 Has anyone else run into this, and found a quickfix that works? I tried dumping the database, changing the id columns from INT to BIGINT, but got a foreign key error when loading the database back in. I have tried to Google this problem, and several solutions suggest turning off foreign key checks temporarily. How risky would that be? Best regaqrds, Magnus Enger Libriotech AS
