Flexible Freeze fails on schema-qualified table names

[nickgsc]

If your database has multiple schemas, and the base query detects one of these tables needs to be vacuumed, it fails because the schema-qualified table name is being wrapped in double quotes.

The failure looks like the following:

2022-08-09 14:20:52 UTC: VACUUM FREEZE ANALYZE "schema.table" in database dbname
2022-08-09 14:20:52 UTC: VACUUMing schema.table failed.
2022-08-09 14:20:52 UTC: relation "schema.table" does not exist

Thanks for the report and the PR! There is definitely an issue here with tables that are not in search_path. The proposed PR would fail if a table had "A Name That Needs Quoting", so more work is required there. We'll see about fixing that.
