Create your SQL scripts that define the functions in a make
step, invoking sed(1) to substitute a constant string with
the content of an environment variable. This worked for the
past 20 years and I'm sure it's extremely portable.

You don't need to DROP and reCREATE the functions and type if
you just fixed some bug in the C coding. Recompile it,
replace the shared object and reconnect to the database. The
new backend (you get at reconnect) will load in the new
shared module and use the new code.
