One column value doesn't necessarily mean one tuple unless it has a unique index on that column. SELECT COUNT(*) FROM table WHERE field = 'value'; That's perfectly reasonable. You don't need the GROUP BY clause. However, this doesn't sound like a hackers question. Next time, please ask on another list such as pgsql-sql or even pgsql-novice.
