Hello

it looks like known issue of sometimes dysfunctional plan cache in
plpgsql in 9.2.

similar issuehttp://postgresql.1045698.n5.nabble.com/Performance-problem-in-PLPgSQL-td5764796.html
Thanks for the link ) I read about issue, but I can't understand what should I do?


You can do nothing. You can check, so described issue is same as your issue, and that is all :(.

It is bug in plan cache implementation.
