Add functions pg_restore_relation_stats(), pg_restore_attribute_stats().
Similar to the pg_set_*_stats() functions, except with a variadic
signature that's designed to be more future-proof. Additionally, most
problems are reported as WARNINGs rather than ERRORs, allowing most
stats to be restored even if some cannot.
These functions are intended to be called from pg_dump to avoid the
need to run ANALYZE after an upgrade.
