i've read the FSF writings about GPL and interpreters multiple times and
still i don't understand the exact meaning (or even what they would like
to enforce). _my_ interpretation is that as long as you don't directly
link with psycopg and only use the python api you're safe. you can write
and distribute a proprietary python program as long as python and any C
module calling psycopg are GPL compatible. you can even have proprietary
C module in python as long as they don't call psycopg code (by "linking"
i mean linking, not just coexisting in the same address space :)
