Support Postgres non-reserved words

[zoaha]

if you have something like

VACUUM (ANALYZE, VERBOSE, FULL) tablename;

it will break the formatter but it's 100% valid query.

not sure, but I think everything here: https://www.postgresql.org/docs/current/sql-keywords-appendix.html
where the 2ne column (PostgreSQL) with a value of non-reserved should be added?

This failing to parse for Postgres has nothing to do with non-reserved keywords. It's simply that support for VACUUM statement has not been implemented at all in the Postgres parser.

FYI, you can use conditional comments to work around this lack of support:

/* sql-parser-cst-disable */
VACUUM (ANALYZE, VERBOSE, FULL) tablename;
/* sql-parser-cst-enable */
