Database initialization code hangs on terminate open connections

[bubblesnet]

Following line hangs sometimes:

sudo PGPASSWORD="$POSTGRESQL_POSTGRES_PASSWORD" psql -h "$POSTGRESQL_HOST" -p 5432 -c "SELECT pg_terminate_backend(pg_stat_activity.pid) FROM pg_stat_activity WHERE pg_stat_activity.datname = '$POSTGRESQL_APPLICATION_DBNAME' AND pid <> pg_backend_pid();" "user='$POSTGRESQL_POSTGRES_USER' dbname=$POSTGRESQL_APPLICATION_DBNAME password='$POSTGRESQL_POSTGRES_PASSWORD'"

without this line, drop/create sometimes fails because of open connections. Commenting out for now.
