*** 151,161 ****
! Prior to PostgreSQL 7.3, the plan was
! emitted in the form of a NOTICE message. Now it
! appears as a query result (formatted like a table with a single
! text column).
--- 151,162 ----
! Genetic query optimization (GEQO) randomly
! tests execution plans. Therefore, when the number of tables
! exceeds geqo> and genetic query optimization is in use,
! the execution plan will change each time the statement is executed.
