We are certainly not going to buy into the assumption that our snprintf
has to support every odd feature that anyone anywhere thinks snprintf
should have :-(. The correct response to this is to figure out how your
program's calls got linked to our snprintf, and stop that from
happening.

AFAICS, our library should be defining the global symbol pg_snprintf not
snprintf. Can you look into why that's not happening for you?
