Assuming your packaging is correct, the no module named psycopg2 error typically indicates the binary file(s) of your psycopg2 deployment is incorrect for your target OS or Python version.

For Lambdas, we have found that the psycopg2 binary works (using manylinux_x86_64). There is a reported risk of segfault due to the presence of competing libssl binaries though we haven't had that yet. (this is basically a +1 for jshammon's answer above)

The "proper solution" is probably jkehlers recompile specifically for Lambda missing only lib_pq.so, but it doesn't currently support ssl+py3.7 and we are too Windows to recompile it ourselves.
