db:pull fails in Postgres if database with same name as current user does not exist

[kiddrew]

The workaround for this is fairly simple, but it's an issue nonetheless. If my local Postgres instance does not have a database with the same name as my current user, the db:pull command fails. See below:

The issue is this line:

psql -c "SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity WHERE pg_stat_activity.datname = 'ilfcms_development' AND pid <> pg_backend_pid();;"  -U andrew  -h localhost  -p 5432
