What would be the most common? pl/python only comes in untrusted form, so
can only be used by the superuser. I think that rules it out as a general
recommendation. And SQL and PL/pgSQL don't solve the problem. Are there
any outside-of-standard-distribution languages which could qualify as
common?

I'd rather see the specific recommendations than just be tossed at
https://www.postgresql.org/docs/current/xfunc.htm and left to click around
until I eventually land somewhere useful to the task at hand. Maybe it
could direct to https://www.postgresql.org/docs/current/xplang.html?
