If we provide 'external initializer', some of your proposals can be done
through more generalized way, at least the foreign key test. It is a
replacement of the DDLAFTERs[], which is a hard-codeded list in the source
code to create primary keys. It may help other people, for example, who want
to test the performance of hash index instead of btree index (primary key).
Using it, you can use the below script or something:
$ pgbench -i -f init_with_fkey.sql
[init_with_fkey.sql]
alter table branches add primary key (bid);
...
alter table tellers add constraint tellers_bid_fkey foreign key (bid) references branches (bid);
...
Are you interested in this idea?
