I've been using PostgreSQL from Guile for the Guix Data Service [1]
stuff, guile-dbd-postgresql didn't work out, I can't remember exactly
why, but I think it could have had something to do with error
handling/reporting. Anyway, guile-squee seems to do the trick.


I'm interested in doing some Cuirass stuff, but I'm still a little
uncertain about how you might go about that. I think there's probably
some easier related tasks though.

One thing that I saw related to Sqlite is that the rowid's that Cuirass
does use behave differently if there's an INTEGER PRIMARY KEY column in
the table [2]. This is important I think, because without this,
operations like VACUUM can change the rowid's [3]. I think Cuirass uses
rowid's as the identitifers for builds for example, but not in this
