Nope. ANALYZE collects some statistics (for example an estimated number 
of rows on each table... this number is available in pgAdmin under the 
exact number of rows).

The Count item of the contextual menu does a count(*) on the table. So, 
it gives you the exact number of rows.

No. You really need to select the menu item "Count" to have the exact 
number of rows.
