Having done this (building a - limited - code generator framework using
bash+psql+plpgsql) I will say that doing so using pl/pgsql, while appealing
from "no extra tooling needed" perspective, doesn't play to pl/pgsql's
strengths. Using a different language to generate SQL script files, which
can then be executed, is probably a better way to go - if you have a
different language you can build upon (i.e., not a shell scripting language
like bash).

In particular, plpgsql nested strings are not fun to work with in any
significant volume.
