Trustly Group AB is a Swedish financial institute under the supervision
of the Swedish Financial Supervisory Authority. Trustly processes
millions of physical bank transactions on behalf of its clients.
The entire back-end system at Trustly is written using stored procedures
in PostgreSQL, mainly PL/pgSQL but also pure SQL and PL/perl.
Trustly has successfuly been using PostgreSQL since 2008, and
managed to add new services, banks, countries, currencies,
customers and external payment processors to its system, without
outgrowing PostgreSQL to do all the bookkeeping and business logic.
Relocation to Stockholm is be necessary, but it's a great place
so shouldn't be a problem for any sane person.
