They are coming from an install of psycopg2-binary:

pip install psycopg2-binary

Looks like something is setting up psycopg2-binary and psycopg2 as part 
of some script/tool/orm/etc in your $DATA directory.

Are you using something that uses psycopg2 as the client library?

You are  going to have investigate what is actually repeatedly 
installing psycopg2-binary and psycopg2.

Steps I can think of to do this:

1) Sort the temp directories by timestamp and see if there is a pattern.

2) Look at the OS system log for entries at the above timestamps.

3) Do same for Postgres log.
