Ah, excellent point. If we consider only fragments of SQL then yes,
the problem gets way smaller.

Dunno, I'm not seeing a warning there either. Perhaps that zwsp
dates from before one of the mass reformattings we've done over
the years? I didn't bother doing any archaeology though.

Great idea, but when I looked at the rendered A4 PDF I saw why we'd
put in the zwsps: without them, FOP decides that the best way
to break these lines is like
uuid_extract_version('41db1265-8bc1-4ab3-992f-885799a4af1d'::u-
uid)
which of course is really horrid (cf first attached screenshot).
However, adapting your idea a bit, I tried putting spaces around
the "::", and that renders far better (cd second attachment).
So I'll run with that.
