A schema shipping a custom text search dictionary (taiga's english_stem_nostop) survived the pre-clean and aborted the dump replay with a duplicate pg_ts_dict_dictname_index violation under ON_ERROR_STOP. The discovery SELECT now also enumerates user-owned pg_ts_config and pg_ts_dict entries. The string-assertion unit test is replaced by real scenario data in the e2e: the seeded schema now contains an overloaded f()/f(int) pair and the nostop dictionary plus configuration, and the restored database is queried to prove each survives the backup, pre-clean and replay cycle exactly once.

One DO-block ran every DROP in a single transaction and exhausted
max_locks_per_transaction on large schemas (gitlab); emit one DROP per
row and execute via \gexec instead. Also drop user-owned non-public
schemas so a dump that CREATE SCHEMAs (discourse) does not abort on the
existing schema under ON_ERROR_STOP.
Covered by a new DinD e2e test restoring --empty against a fully
populated database with a non-public schema and every object class.
