Description:
The mysql_list_dbcolumns() and insert_fields() functions unnecessarily retrieve all rows from a table.

How to repeat:
Call SQLColumns(), or just look at catalog.c (mysql_list_dbcolumns) and cursor.c (insert_fields).

Suggested fix:
Add LIMIT 1 (or LIMIT 0) clauses to the statements these functions are generating.
