I’verecently found myself wishing I could specify multiple tables in a single VACUUM statement. For example, this
wouldbe convenient when there are several large tables in a database and only a few need cleanup for XID purposes. Is
thisa feature that the community might be interested in?
I'm a bit surprised to realize that we don't allow that, since the
underlying code certainly can do it.
You realize of course that ANALYZE should grow this capability as well.

parameterin the VACUUM grammar to a qualified_name_list. While this fits into the grammar decently well, I suspect
thatit may be desirable to be able to specify a column list for each table as well (e.g. VACUUM foo (a), bar (b)).
The column list only matters for ANALYZE (or VACUUM ANALYZE). But yes,
it should be per-table.
