on my databases, i have only been successful in doing a "VACUUM VERBOSE" on
my tables.

i suspect i've got the syntax wrong or something:

nagoss=> \h vacuum
Command: vacuum
Description: vacuum the database, i.e. cleans out deleted records, updates statistics
Syntax:
        VACUUM [VERBOSE] [ANALYZE] [table]
        or
        VACUUM [VERBOSE]  ANALYZE  [table [(attr1, ...attrN)]];

nagoss=> vacuum verbose analyse switches;
ERROR:  parser: parse error at or near "switches"
nagoss=> vacuum verbose switches;
NOTICE:  --Relation switches--

VACUUM

what is the correct syntax for doing a vacuum analyse?
