vacuumdb would use a catalog query only when the command caller does not define a list of tables. Switching to a catalog table represents two advantages: - Relation existence check can happen before running any VACUUM or ANALYZE query. Before this change, if multiple relations are defined using --table, the utility would fail only after processing the firstly-defined ones, which may be a long some depending on the size of the relation. This adds checks for the relation names, and does nothing, at least yet, for the attribute names. - More filtering options can become available for the utility user. These options, which may be introduced later on, are based on the relation size or the relation age, and need to be made available even if the user does not list any specific table with --table.
