d32d146399 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.

4b096c67e0 Improve pg_set_attribute_stats() error message.
Previously, an invalid attribute name was caught, but the error
message was unhelpful.

ce207d2a79 Add functions pg_set_attribute_stats() and pg_clear_attribute_stats().
Enable manipulation of attribute statistics. Only superficial
validation is performed, so it's possible to add nonsense, and it's up
to the planner (or other users of statistics) to behave reasonably in
that case.

779972e534 Disable autovacuum for tables in stats import tests.
While we haven't observed any test instability, it seems like a good
idea to disable autovacuum during the stats import tests.

b391d882ff Allow pg_set_relation_stats() to set relpages to -1.
While the default value for relpages is 0, if a partitioned table with
at least one child has been analyzed, then the partititoned table will
have a relpages value of -1.

e839c8ecc9 Create functions pg_set_relation_stats, pg_clear_relation_stats.
These functions are used to tweak statistics on any relation, provided
that the user has MAINTAIN privilege on the relation, or is the database
owner.
