Обсуждение: vacuum analyze syntax in psql' help

vac=> \h vacuum
Command: vacuum
Description: vacuum the database, i.e. cleans out deleted records, updates statistics
Syntax:
vacuum [verbose] [analyze]
        or
vacuum [verbose] [analyze] table [analyze [(attr1, ... attrN)] ];
                                  ^^^^^^^
Imho, new ANALYZE syntax with attributes is quite unclear to me:

vac=> vacuum x (y);
PQexec() -- Request was sent to backend, but backend closed the channel before responding.
        This probably means the backend terminated abnormally before or while processing the request.

How about the next:

Syntax:
vacuum [verbose] [analyze] [table]
        or
vacuum [verbose] analyze table (attr1, ... attrN);

Oops, forgot to remove that second analyze.

Will you fix this ?

And this ?

Vadim

Done.  Manual page, psql help, and error message fixed.
