We at Postgres Pro use the attached fop-config.xml (passed to fop as "-c
.../fop-config.xml"). Please try it and see, whether the glyphs rendered
as expected.
You can also look at the generated pdf:
https://postgrespro.com/media/docs/postgresql/12/en/postgres-A4.pdf
But π (pi) is still rendered unusual as you can see on the page 179, so
I would prefer the symbol font anyway.

Best regards,
Alexander
