I think this has more to do with pgsanity:

https://github.com/markdrago/pgsanity

"So the approach that PgSanity takes is to take a file that has a list
of bare SQL in it, make that file look like a C file with embedded SQL,
run it through ecpg and let ecpg report on the syntax errors of the SQL."

A quick look through:

https://github.com/markdrago/pgsanity/blob/master/pgsanity/sqlprep.py

which is where the passed in SQL string is processed into ecpg format
does not show that it deals with variables. So you might to take this up
with the pgsanity author.
