+# Postgres
+## Psql
+
+Use the `build.sh` script to download and build `psql`.
+The resulting `psql` binary is a static PIE executable loadable using the Unikraft ELF Loader. 
+Launching psql with run_elf_loader, it is required to launch with the `-U <username>` parameter, because Unikraft does not provide a default user to `psql`.
