 The generated `install_<version>.sh` recipes also accept `--help`/`-h` and can be run from their saved component source directory to repeat that component's configure/build/install steps.
 
+## Resuming a failed extension build
+
+If an extension build fails, rerun that extension's standalone installer with the same PostgreSQL version and installation prefix. The standalone installer rebuilds only that extension and preserves the installed PostgreSQL prefix. For example, to retry HypoPG for PostgreSQL 17.11 installed in a custom prefix:
+
+```bash
+PREFIX=/app/staging_area/postgres/rdbms/17.11/ ./install_hypopg.sh --version 17.11
+```
+
+Replace `install_hypopg.sh` with the failed extension's installer, and use the prefix where PostgreSQL is installed. If you used the default prefix, omit `PREFIX`:
+
+```bash
+./install_hypopg.sh --version 17.11
+```
