The use case is psql scripts which update or cleanup an application 
schema. For security, some of these scripts check for conditions (eg, we 
are not in production, the application schema is in the expected version, 
whatever…) and should abort if the conditions are not okay. As checking 
for the conditions requires a few lines of code and is always the same, a 
simple approach is to include another script which does the check and 
aborts the run if necessary, eg:

```sql
-- this script should not run in "prod"!
\ir not_in_prod.sql
-- should have aborted if it is a "prod" version.
DROP TABLE AllMyUsers CASCADE;
DROP TABLE QuiteImportantData CASCADE;
```

The intention of the user who wrote the script is to abort in some cases, 
to avoid damaging the database contents.
