Rather cool “delete all data from a #PostgreSQL database without dropping the ‘public’ schema and without being a superuser” which I just wrote for ⮡ tarent. Feedback & improvements welcome.
I’ve also got a “delete everything except these two tables, and everything (sequences, constraints, indicēs) belonging to them” version.
These are especially useful in a scenario where you have an application server with one PostgreSQL cluster on it, in which one or multiple databases with just one schema each are configured (the database may also run on a separate VM than the application itself), which is the default setup for most applications using
dbconfig-common (Debian), Flyway or Liquibase/DB-Manul, or other (semi‑)automatic schema management (e.g. the one in VerA.web), especially when the DB schema version of the dump is not the same as the DB schema version of where you want to restore it into.
