> Looks a nice feature. Btw, (just a question) Any system you referred to
for defining this syntax?
PostgreSQL syntax is:
```
ANALYZE [ ( option [, ...] ) ] [ table_and_columns [, ...] ]
ANALYZE [ VERBOSE ] [ table_and_columns [, ...] ]
where option can be one of:
VERBOSE [ boolean ]
SKIP_LOCKED [ boolean ]
and table_and_columns is:
table_name [ ( column_name [, ...] ) ]
```
This syntax (` ANALYZE TABLES ((FROM | IN) multipartIdentifier)? COMPUTE
STATISTICS (identifier)?`) is from
