Hi Florian,

You are indeed correct.  Setting nointr also resolves my issue.  I could swear I checked this, but obviously not.

It does still concern me that pgsql did not deal with this as gracefully as other software.  I hope the list will
considera patch to resolve that. 

Thanks in advance,

George
