Yorick Peterse 79696f5b7a Hash concurrent foreign key names similar to Rails ... This was initially not implemented simply because I forgot about the size limit of constraint names in PostgreSQL (63 bytes). Using the old technique we can't add foreign keys for certain tables. For example, adding a foreign key on protected_branch_merge_access_levels.protected_branch_id would lead to the following key name: fk_protected_branch_merge_access_levels_protected_branches_protected_branch_id This key is 78 bytes long, thus violating the PostgreSQL size requirements. The hashing strategy is copied from Rails' foreign_key_name() method, which unfortunately is private and subject to change without notice.		2017-02-21 15:07:02 +01:00
