I want to glue some of this pipe, which I presume is uPVC. It's a
pinhole. The solvents in the usual solvent weld things are not usable
in this case, so I'm looking at glues. It needs to tolerate water,
and it can't be decomissioned for repair, so has to cope with slight
seepage at near zero pressure during application. It doesn't need
heat tolerance.

Would epoxy or epoxy putty do the job, after roughening the surface?

Yup - a two part plumbing repair putty ought to.

Failing that, see "plumbers gold" from toolstation - its a MS glue /
sealant that will stick to anything and set underwater.
