Based on PostgreSQL documentation research (postgresql.org/docs/current/app-pgrestore.html):
CRITICAL FIXES:
- Add --exit-on-error: pg_restore continues on errors by default, masking failures
- Add --no-data-for-failed-tables: prevents duplicate data in existing tables
- Use template0 for CREATE DATABASE: avoids duplicate definition errors from template1 additions
- Fix --jobs incompatibility: cannot use with --single-transaction per docs
WHY THIS MATTERS:
- Without --exit-on-error, pg_restore returns success even with failures
- Without --no-data-for-failed-tables, restore fails on existing objects
- template1 may have local additions causing 'duplicate definition' errors
- --jobs with --single-transaction causes pg_restore to fail
This should resolve the 'exit status 1' cluster restore failures.
