Hi again,

Attached is a more complete first attempt at adding this functionality. I added two node types: one for parsing the “relation and columns” list in the grammar, and one for holding the relation information we need for each call to vacuum_rel(…)/analyze_rel(…). I also added assertions and comments for some undocumented assumptions that we currently rely upon.

Adjustments to the documentation for VACUUM/ANALYZE and new checks in the VACUUM regression test are included in this patch as well.

Looking forward to any feedback that you have.

Nathan
