My next proposal for the syntex is "VACUUM (options) table_name".
Since "options" are quoted by '(' and ')', we can add new options
without adding them into reserved keywords.
The traditional vacuum syntax:
VACUUM FULL FREEZE VERBOSE ANALYZE table_name (columns);
will be:
VACUUM (FULL, FREEZE, VERBOSE, ANALYZE) table_name (columns);
I think the syntax is consistent with existing syntex of "EXPLAIN (...)".
We can choose any keyword for the new "rewrite" version.
For example:
* VACUUM ( REWRITE )
* VACUUM ( FULL [ INPLACE | REPLACE ] )
