Right.  It's just a matter of checking how cuirass does it and do the
same in guix-forge.

Right.  Postgresql makes sens for huge CI like ci.guix.gnu.org I guess.
However it would indeed be nice to have the option to select sqlite as
the DBMS.  For the Guile portion that should be trivial I think.  The
difficult part is probably within the SQL schema, if Postgresql'
extensions were used.  Maybe the solution would be to use a
object-relational mapper and generate the schemas on the fly depending
on the DBMS.  I think that `guile-dbi` does just that.

To continue :-)
