Hello Martin, All that I can add to your question is, that both messages for PIPE_IO will not cause any problems, but they aren't marked with WNG too. So maybe that is nothing new. The database kernel is only testing, how a a pipe has to be checked for available data on your system.

Since all my schemas on this instance lost their indexes some time ago (I am still investigating), I wonder if these warnings are important, and if they are, should I use ulimit or something like that to solve it??
