Description

The postgres database is built and running fine. Then I tried the following two lines:
psql -f postgres-functions.sql -d mimic
bash postgres_make_concepts.sh

I get many of the following error messages repeatedly (the only table that doesn't produce this error and actually gets created at the end is the diagnosis table).
sed: 1: "s/DATETIME_DIFF((.+?), ...": RE error: repetition-operator operand invalid
sed: 1: "s/`physionet-data.(mimi ...": RE error: repetition-operator operand invalid

I could not find related issues either open or closed - thanks!
