I know this post is a few months old now, but I have a strikingly similar setup and am getting a similar, somewhat more reliable error: ERROR: could not open file "base/29292/12186914_fsm": Invalid argument It happens while doing an ST_Difference() function on two large geometries. I'm running OSX 10.8 (Mountain Lion) Postgresql 9.4.1 PostGIS 2.0.1 It's failing repeatedly for me right now, so at the moment it's a hard fail. That said, just last week, with the same database, same command but different table, I got this slightly different error: ERROR: could not open file "base/29292/49722_fsm": Invalid argument THAT error, however, cleared up mysteriously after I shut down and restarted. (I haven't been able to get tonight's error to clear up in the same way.) What other information can I provide to help track squash this bug?
